back off jerk

So I'm in a certain pass/fail class that requires us to do a bunch of role plays to practice different parts of a trial. Now keep in mind, the class is PASS/FAIL. We don't get graded based on the number of words we utter in each class period. Today we were practicing getting exhibits submitted into evidence. As I go through these assignments, I object to obvious things, but most of us have other things to get to and we just try to move through the assignments as quickly as we can without being rude. However, today I got stuck working with someone that I do not normally work with. This person, for whatever reason, decided he needed to object to practically every word that came out of my mouth. Now I understand that we are doing this so that we can practice for when we have to do this in real life, but do we really need to badger our classmates just so that we can feel superior? These egos are one of the things that make me really dislike law school some days. I know that these are the types of people that I'm going to have to deal with throughout my life, but come on, give it a rest. You're not as smart or as eloquent as you think, BACK OFF!
