AITAH for spraying something on my roommate's stuff?
I 21F and my roommate 20F live with one other roommate 20F. We've been living together in a small triple dorm for the last year. The first couple of weeks were fine, until we started to notice that our third roommate was specially loud during the morning; she would wake up everyday, including weekends, at 6am and wouldn't let us sleep. Eventually, I approached and ask if she could be a little more mindful with her noise, she responded by getting very defensive and seemed to take it personal. My other roommate and I didn't think much about it since qe had previously mentioned communication was important, we just thought of it as a conversation that needed to happen. so later that day we invited her to a party, which she rudely declined the invitation and never spoke to us since that day. She stopped talking to us, but starting doing things that bother both my other roommate and I. For example, she left her dirty underwear on the floor, took most of the space in the room not respective boundaries, would turn on the main light very late at night when we were already asleep, or very early in the morning, she had her parents over regularly with no warning so I would sometimes wake up from my naps with them starring at me, she kept her nightlight on super bright next to me all night, she blasted her music early in the morning, and even organized her dishes while we were asleep. When we finally got sent to roommate therapy, she refused to take accountability for anything and didn't want to compromise to anything either, instead she turned it on us and said we were the problem, forbid us from yawning as she dimmed it a loud noise, and said guests were not allowed, which was sad because my roommate lives like 7 hours away from home and because of this she couldn't see her boyfriend until Christmas. While we tried compromising on these, even if they were kind of unreasonable, she was still mad and even told our RA that we were the drama and that's why she had blocked us on instagram, she went as far as getting a curtain to "hide", her words not ours, but she never closes it, causing my other roommate to sometimes see her changing her clothes in front of her, not respecting her boundaries. As for me, because we sleep directly in front of each other, sometimes I wake up and she's directly starring at me, making me uneasy. She also lock us out of the room by slamming the door in our faces when we leave the door cracked for a moment while we use the bathroom, but she keeps the door wide open any time she leaves for long periods of time, even when we're asleep. With all of this said, and with she constantly disrespecting us and our boundaries without any accountability, we decided to a little innocent payback, now that the year is coming to an end and we're tired of her: we got a fart-spray and have been spraying it in tiny amount in stuff like her chair or her laundry basket, and she has noticed it. AITAH?
