I know I'm going to get angry over drinks tonight with my friend.
Do drinks make you angry?
I'm going drinking with my friend who always talks behind my back, he makes up things about me and pisses me off.
He shouldn't be doing that. But it's best to stay calm when you see him. Maybe you should consider ending the friendship.
Maybe, I'll think about it.
Yeah, the next time you are with your friend, take a step back and decide if this person is really someone that you want to spend your time with. You might decide that the best thing is end the friendship and that's perfectly okay.
