Everybody can be a jerk sometimes.
What I like to do, when someone is being a jerk to me, is...take a look at myself first, to see if I started acting like a jerk before they did.
If the answer is yes, then I apologize and get my act together.
If the answer is no, I sucker punch- I mean, I um...I don't actually know, because I'm still laughing about the idea of me punching anyone.
Sorry to be of so little help.
