I'm going to leave my possibly drunk friend to drive herself home because she was being too controlling and mean
Why do you want your drunk friend to drive herself home?
I'm just tired of her shit.
It is frustrating to have to spend time with somebody who is controlling and mean but you shouldn't let her driver herself drunk. If she gets in accident and hurts somebody you might feel guilty.
Ugh, I'll ask her if she is drunk and make sure she drives carefully.
Good, even if you don't want to drive her if she is drunk you can always call her a ride instead.
