I feel like I'm gonna kick my new roommate's bf out of the apartment at 2am.
Why would you kick them out in the middle of the night?
He drank out of my coke bottle.
While it's expected that people respect your property, you shouldn't kick someone out in the middle of the night. They may not have anywhere else to go. Or they could be too tired to get home safely.
I'm going to do it anyway. I want to cause him as much inconvenience as I can.
I think you are overreacting just a tad here. You should just talk to them about it in the morning.
