Closed my bedroom door with me inside it as if to say "you'll go to bed now". I don't know why, but this triggered me.

Had a buddy stay with me and my then GF now wife, lived on the top floor of a poorly insulated apartment. We never set the air below 75 in the summer (kept it at 70 when we first moved in and got a $300 bill) we came back from being out of town for a few days he has some chick naked on the couch (my wife hated this girl and he knew it) and the air was set to 65. He didn't live there much longer.

My father in law was staying with us for a month, he lived in Oman. The spare room was an office with a sofa bed in so it could double up for guests. He bought a double bed and got rid of the sofa bed. I lost my office.

My wife 3 days ago. Tasked with feeding her friends cat while they're away for a week. They said help yourself to whatever you like. She came home with their waffle maker. Pretty sure it meant she could score a couple of their Tim tams not make off with their appliances

Picked up sister and BIL from airport and dropped them off at my house before taking my preschool kid to a doctor’s appointment. Told them to make themselves at home, we’ll be back in 2 hours. They at all the snacks in the entire house, including 10 brand new boxes of Girl Scout cookies. At least 2 months worth of snacks. They laughed and said they “just couldn’t help themselves since they don’t have junk food in at home”. Worst part? Girl Scout cookie season had ended two days before. All those delicious Thin Mints, gone.

Had a friend stay until he found a job and got on his feet. He never applied anywhere, or tried to leave our couch at all. Another friend offered him an interview and he purposely blew it because he didn’t like that job. He was mean to my puppy and sat in our house all day while we worked and never offered to take her out or anything. The worst though is when he started blaring the tv at 5am. I mean literally almost as loud as the tv would go. And he was always f**king watching Scrubs. He left around a month and a half later after he ran out of money from ordering food for every meal and not leaving our house. He then made a post on Facebook about how the city defeated him and it didn’t work out lol

My husband’s old friend stayed with us for two weeks while we were living in Japan. He was very smug and irritating; an instant ‘expert’ on Japan after a few days, when we had been living there for two years. Finally, finally he left on a Friday. My husband and I had separate plans on Saturday. I returned in the afternoon to an unlocked door and the sound of the TV. I thought hubby had returned early. Nope. It was Old Friend - thinking we had gone for the weekend, he had broken into our apartment for an extra two-night stay. “You weren’t supposed to be here!” he protested - and he refused to leave until my husband came back home and told Old Pal personally that he had overstayed his welcome.

An in-law took about a 28 minute shower after I explained we were in the middle of a drought and that our well was dangerously low. I’m assuming it was going to be a 30 minute shower but we ran out of water.

Dinner guest asked to stay overnight because of the snow (which wasn’t forecasted until much later that night). Spouse and I agreed as we didn’t have work the next day. But guest did - and at 7:30 in the morning he was freaking out because we hadn’t shoveled the driveway for him yet. “How am I supposed to get to work on time?!”

I let my sister stay at my house after her breakup. She told my 5 year old to clean up his "f**king bath toys". They were in HIS bathroom that we let her use as well. That's not even the half of it I don't speak to her anymore

My brother's best friend came to live with us for "a few months" because he wanted to move back to our state. My parents agreed because he was supposed to go to college and they believe college education is important. Well 8 years later and he is still there, all my parent's children have moved out but for some reason my brother's best friend is still living there.

I had a longtime friend who was just sort of chaotic and oblivious as a teen, super messy bedroom, yadda yadda pretty normal for a teenager. But as we all got older she never seemed to grow out of any of it. So by the time we are in our late 20s, I started to dread getting together with her because just getting together for dinner or drinks on Friday meant essentially committing to her staying the entire weekend. The final straw came one Monday when I had to get up to go to work (I was also a full time student) and she was still hanging out. I told her goodbye and made it clear I wasn't coming back because I had plans after work. When I finally got home that evening, the house was in shambles. She'd managed to tear down the shower curtain, just leaving it hanging. She had apparently worn a pair of my favorite slippers, fluffy pink pigs, and managed to rip the tail off one, which she just left lying there on the floor. Dirty dishes, of course. This was the same woman who managed to catch my favorite sweater (hand knit by a former BF's mother) ON FIRE at a bonfire. Burning a giant hole (hand sized) and leaving it covered in scorch marks. She actually tried to hide it by I think putting it back folded. The final straw came at an event for her parents where I was helping out and she literally snapped her fingers at me and told me to "get back to work" when I was having a smoke in the backyard with some other friends. I just never spoke to her again.

He got extremely drunk, told us "Stop me when I start making comments about the Jews," and proceeded to fall all the way down the racism tree hitting every major branch on the way. That's the last time I host a Christmas party with beer, let me tell you.

A friend brought a friend to my house. She and I were preparing food for us to have a meal and he wandered into the kitchen and said "Your computer has a password on it - I can't get on there."

Redecorated the house with religious artifacts. Am an atheist.

Came home, sitting in his boxers on my kitchen counter washing his feet and trimming toenails in my sink has got to take the cake.

My ex-BIL plopped himself and a plate of bbq ribs on my nice, cream-colored sofa, and he proceeded to chow down. He used the sofa as a napkin, spilled the meat on the sofa, and I kid you not, I actually had bbq sauce on the ceiling above where he was sitting. HOW do you get that stuff up there? Here I am, two decades later, and I still have not figured that one out.

My relative stayed with my grandma and proceeded to burn the house to the ground by deciding to have a bon fire 3 feet from the side of the house.

I had guests turn the pool heater on in February and not turn it off or tell me it was on. I noticed steam coming off the pool a week later and it was 90*F. The bill was just under $1000.

I got my guest settled on the couch for the night, and I woke up to them right next to me, and sound asleep in my bed.

Rearranged my kitchen. That b***h. it wasn't my mom. It was a guy I'd gone on two dates with that I left alone in my apartment for a few hours. My mistake I guess.

I’ve had relatives eat all the food in our fridge, use our house to play host to people they know in our city. They also broke our screen door and had no remorse whatsoever. It was presented as “oh your screen door is broken!”

I came home from work that day and my homie was there. With his girl and 4 kids for weeks in my 1000 sw foot house. Ate all my food and wouldn't leave me alone until I drove them 10 hours away to some family's house

My sister stayed with our brother and dad a few years ago while bumming around (her husband passed away and she doesn't have to work, so she travels pretty much year round). While there, without anyone's permission and at no one's request, she completely dismantled and reorganized their walk in pantry, threw all of their food because it was "too processed" and "not healthy enough" (it was basic stuff too... pasta, sauces, frozen pierogies, potatoes, canned goods, snacks, etc.) and bought new. After her trip to the grocery store, she had the audacity to try and charge them for the food she bought. It wasn't even stuff they particularly liked, which cracked me up. They laughed in her face and she sulked for like a week. Then she invited her teenage son to stay with them because he got kicked out of camp? school? something like that for vaping, and she was "too mortified" to let him back home so early. At the time, my brother lived 2 states away, lol. After that, she overstayed her welcome by about 3 weeks. Needless to say, she's a hot f**king mess.

He literally took his freaking socks off and put them on the dining table. Dude... what?

Sister's friend carved her name into our wall and porch

We have a 9-year-old little girl from down the street who's friends with my daughter. She comes to our house at least every other day, and mostly just shows up. She has an opinion about EVERYTHING we do. My wife or I can not make a move without feeling judged, or receiving some advice I would never expect from a 9-year-old, ranging from how messy our house is, to how we spend our money. And she talks back as much as my own kids. It mostly makes us laugh. Mostly.

Deleted all of my passwords off my computer after asking to check her email.

Laid a lit cigarette on a ornamental wood box that I gave my SO on his birthday. The next morning after he left my SO found the box with the burnt cig and melted filter still laying on the box.
