23-year-old kicks out her sister, Amelia, and 5 friends after discovering Amelia has been using her apartment for parties and telling everyone it's her home

• Living alone for the first time is one of those milestones that feels genuinely good in a way that's hard to explain to someone who hasn't done it yet. Your own space, your own rules, your own furniture exactly where you put it. It's a small kind of freedom that matters a lot.

• AITA for kicking everyone out after my sister lied and said my apartment was hers?

  I (23F) live alone in a decently nice apartment, and i’m proud of it. My sister, “Amelia” (20F) lives at home, we’ve always been very close so I gave her a key for convenience and emergencies.

• Since I moved in about 10 months ago, Amelia has been coming over a lot. At first it was nice, but now it’s almost daily. I work long hours and value my space and privacy, so this has been a little frustrating for a while, but I tried to be understanding because I know she really wants to move out too.

• Over the past 2-3 months, Amelia’s been obsessed with my apartment and its “aesthetic”. She constantly comments on how she would decorate differently or suggests that “we” should move furniture around. I usually brushed it off as jokes.

• It didn’t really start to get weird until I started coming to her in my apartment after letting herself in while I wasn’t home. A few times I had noticed she rearranged little things, it bugged me but I didn’t outwardly confront her because it wasn’t worth a fight with her.

• About two weeks ago, Amelia and I were at a mutual friend’s party and I overheard her talking to someone about “her new apartment”, and when I walked up her friend said something like “it looks nice from the pictures”. Which made me think she was showing people my place and telling them it’s hers.

• A few days later I came home early from work and she was on my couch with a girl i’ve never met. Amelia looked obviously shocked and left quickly to “go shopping”. It happened AGAIN a few days later with our two cousins instead, but she didn’t seem to care that I came home this time. I texted her later and asked her to ask me before inviting anyone over to MY apartment, and all she said was “K”..

• After that I assumed all was well, she was still over a lot, but she was acting… oddly nice. I found this weird and was immediately suspicious, but from what I could tell she wasn’t doing anything strange. Boy was I wrong.

• Last night I came home after a 12 hour shift and she was there again. But this time, with FIVE friends playing a drinking game in my living room. I was exhausted and LIVID.

• I told them all to leave. Amelia tried to talk to me in the kitchen but I wasn’t having it, I told them again to leave and one of her friends asked why I was there. In MY apartment. I lost it. I yelled “because I live here. Amelia lives with our parents now get the f out”

• They left quickly but my family is now saying that I embarrassed her in front of her friends, and Amelia is “humiliated”. I honestly don’t think I did anything wrong, but my family is saying my sister is devastated. I’m not even sure what to do from here. I tend to overreact sometimes, but this was wild. And very out of character for my sister.

• AITAH?

  Edit: update coming hopefully tonight! Yesterday I went over to my parents and confronted them and my sister. I work long hours so I haven’t had much time to post the last few days.

• Giving a sibling a spare key is a gesture of trust. It's for emergencies, for convenience, for the kind of casual closeness that makes having a key feel like a nice thing rather than a liability. It is not, by any reasonable interpretation, a timeshare arrangement or an open invitation to redecorate.

• The slow escalation is what makes this kind of situation so hard to address in real time. It starts with someone coming over a lot, which is fine. Then they're rearranging small things, which is annoying but not worth a fight. Then they're bringing strangers over while you're at work, which is a problem. Then they're telling people at parties that the apartment is theirs, which is a different category of thing entirely. Each step is slightly worse than the last, but the gap between any two steps feels small enough to let slide, and by the time the full picture is visible someone has six people playing a drinking game in your living room after you worked a twelve-hour shift.

• The psychological component here is genuinely strange. Showing photos of someone else's apartment to friends and describing it as your own isn't a joke or an exaggeration, it's a constructed alternate reality that requires active maintenance. It means keeping the stories straight, controlling who comes over and when, and managing the risk of the actual resident showing up. That's a lot of effort to put into something that isn't yours.

• Getting caught mid-lie in front of an audience is embarrassing, but the embarrassment in that situation belongs to the person who built the lie, not the person who walked into their own apartment after work. Being humiliated by the truth is a very specific kind of problem that starts well before the moment anyone finds out.
