Coming home from vacation to a $909 bill was definitely not the welcome she expected. While she was away, her roommate entered her bedroom, grabbed her spare keys, and moved her car so a visiting friend could have the prime parking spot. The car ended up in a tow-away zone, but when she returned, neither of them volunteered to cover the cost of their mistake.
I disagree with the OP here: I would never let anyone touch my car. I understand that she left for vacation and told one of the girls that she could use it, and it seemed she was very careful with it and even helped her file a police report so the woman could enjoy her vacation in peace. However, things got out of hand whenever the other roommate decided to take the car and move it so her friend could use that parking spot.
The car got towed and ended up costing $909 to get it back, which is an insane number if you ask me. The worst part? None of the roommates decided to help with the bill, leaving the writer with nothing but tears and a lot of money missing from her account. When things like this happen, the person who is responsible for the mistake should be the one covering the cost.
The community in r/AITAH suggested that she should demand the money from them to cover this huge bill, because it was not her fault that one of the roommates decided to take the spare keys and move the car without hesitation or question. Also, this comes down to respecting others' privacy and personal belongings. No one should be touching others' things without permission because things can escalate and end like this.
