I am no longer in school but I have ran into this situation at work many times. Yes it can wear you down If you chose to own their immaturity. SADLY The best way that I have handle it is to learn to laugh it drives them nuts because they can no longer control your reactions. Do you remember the flip charts that you could create you own animal or person? Wellll we started puting animal faces on them. It got to the point that some even asked what are you smilling about ? But it was ok for me because I was there to do my job and to take ownership of what was mine to keep.When we were in the military this sentince was our motto it is an arcrenim
Be In Total Control of Herself. now we mean no offence but that is what we were called by the guys in our unit. It was a sign of respect with them because we known we could count on each other. good luck
