I'm annoyed by my communist brother
What's wrong with your communist brother?
He called the cops on my friends because them came over to visit.
It's a little unnecessary to call him a communist, but if he's annoying you so much you need to tell on him. If he can't stop on his own then your parents can, you don't need to suffer this much.
Nah, it's fine. I'm going to support him while he continues his way of life. I'll let him down by myself.
You should tell him how you feel about this. It isn't right for him to waste EMS services over a sibling fight.
