Can I threaten to call the cops on my roommates?
Wow, that is extreme. Why do you want to call the cops on your roommates?
They're loud and they've got a lot of guests which makes me angry. It's time to show the guys who's the boss around here
It can be annoying when roommates are loud. You're better off talking to them directly than calling the cops, though. They'll get mad and you could all get in trouble if the cops come.
You are worry too much and think too much about what can happen. Besides I have a lot of friends in the police.
I am just worried about how it can affect you to call the cops. Your roommates can make your life hell for calling the cops on them.
