AITA for refusing to lend a coat to a girl who went out in a crop top in -30°C cold?

It was a dumb decision, I know, but it already happened. Hopefully I can learn from it.<br><br>My wife and I moved into a new apartment a few months ago. It's a new house (about 12 years old) that was split into 3 apartments. We live in the bottom apartment (so it's partly in the basement) and we got a really cheap price for it, because the owners wanted to keep it in the family. Because of this, the owners/landlords are my wife's cousins, and they live in the top 2 apartments. So our living situation is sort of like a family "house", in that we can freely walk into each other's apartments without knocking. It's not something I'm comfortable with, but my wife and her cousins like it this way.<br><br>I (M40) am very much an introvert, so I do have an issue with it when they just walk in without knocking. But it's not something I'm willing to make a huge issue out of. So far, I just found them inside the apartment once. When we go into their apartments, that's (allegedly) only after knocking.<br><br>One of their kids, and I'm sorry if this isn't a PC term, is a dumb as a brick. Mentally handicapped and physically handicapped. Nothing can be done about it, due to a birth defect. Her name is Candy, she's a year older than me, and she's about the mental age of an 8-year old. In our apartment, she'd just wander around opening cabinets and looking inside them, without a reason. Just bored, I guess. I was mildly annoyed by it, when she did it for the first time, and I told my wife to make sure she doesn't do it again. My wife said that I shouldn't take it so seriously, because Candy is mentally handicapped and does not know any better. I said that she still needs to be taught not to do that. My wife said that her sister (Candy's mom) already knows this and she agreed to tell Candy not to do it again.<br><br>This did not happen. The very next time we were all in the same apartment (my apartment), Candy was again just opening cabinets and looking inside them. I was angry, opened the cabinet under the sink, and pretended to be surprised at seeing a (small) scorpion in there. in reality, I just had a plastic toy scorpion in there, and I pretended to scream (silently) in fear when I "found" it, then "bravely" caught it in a glass and threw it into Candy's arms. In reality, I just threw the glass itself at her, without the scorpion. I just wanted to scare her a little and make her stop opening random cabinets. But fuck me very much, she just glassed (non-lethally) her arms on the glass when it shattered on the floor.<br><br>She was not bleeding badly, but her mom took her to the ER just in case. She was very angry and told me to stop picking on a handicapped girl. I was pissed off. If her handicapped sister wasn't so fucking stupid and opened random cabinets without a reason, none of this would have happened. And she knew that I didn't actually throw a scorpion at her. She knew it was all a show from start to finish. But that didn't help.<br><br>Fast forward to last weekend. The whole household decided we should go sledding, and my wife said that I should just swallow my pride and go. I did, and everything went well until we got to the sledding spot. It was fucking cold as balls, windchill of -30°C or so. We were all dressed warmly, me with a parka that's good to -50°C since I live in fucking Siberia. So we're all dressed, everyone has a parka and ski pants and gloves and goggles and face mask and everything. Except one. Candy decided "she's not cold" and went out in a thin shirt, jeans and sandals. With her feet uncovered.<br><br>I pointed out that she'd freeze to death in this cold. Her mom said that she's a grown woman and knows what she's doing, and that she can make her own decisions. In reality, Candy is not a grown woman but an 8 year old in a 40 year old's body. But whatever.<br><br>She obviously froze to death in this cold as balls, and started shivering. Her mom asked if anyone had a warm coat they could lend her. I said yes, but only if she agreed to put actual winter boots on and actual gloves. Her mom said no, Candy hates that, and wanted to know if I could lend her my parka without any conditions. I said no, I will only lend it if she actually puts warm clothes on. Her mom said that I was being an AH, because I was making her freeze for no reason. I said that she would freeze either way, because my parka alone would not be enough to stop hypothermia. And it was already too late, because she already had frosted her hair, which was now like literal glass strands sticking out of her head.<br><br>Her mom was angry and we went home immediately. Now the whole family is angry at me, because I wouldn't lend a coat to a handicapped girl who was freezing. I think it was the right decision, but I'm starting to have doubts.<br><br>Edit: since people are asking about where exactly we live, the answer is central/eastern russia. The temperatures are pretty normal for this time of year, and a warm parka/gloves/boots is the minimum to be dressed for outside.<br><br>Edit2: some people are asking what part of Russia I'm in. I'm in Irkutsk Oblast, on lake Baikal, and it's pretty fucking cold here in the winter. I'm not even joking, it WAS -52°C here just a few days ago. So yeah. Candy went out in just a shirt, jeans and sandals. Literally.<br><br>Edit3: I don't know if anyone is gonna see this, since the thread is probably dead anyway, but I thought I'd update anyway. I'm still being ostracized (sp?) for this, and people are saying that I'm a sociopath. I've seen this exact word used several times, even by my wife. Weird. Also my wife is making demands now, that I need to be more socially accepting of mentally and physically handicapped people. I AM, but she won't let me finish a sentence. So yeah. That's it for now, thanks for your help.
