My roommate is responsible for ruining my sideview mirror and I want them to pay for it.
How are you going to let them know about the money that you need?
I'm going to put a note at his bedside. I know he will sit down on his bed after work, while I'm out with friends.
I'm sorry they wrecked your car, and they should be responsible for all the damages they've done. You are right to remind them in a subtle way, because your property should not be abused this easily.
If he doesn't pay then I'll take steps to make sure he ends up in jail.
I hope it doesn't come to anyone going to jail, but you are correct that your roommate should be responsible for the repairs and the associated costs. He is the one who caused the damages and it's only right he takes responsibility.
