weights class

today in weights class it was extremely boring and i was very tired and did not feel like working out, so i walked out of the weights room and walked down to the gym and started playing some volleyball. Apparantly, Mr. xxxxxxxx does not approve of that what so ever so at the end of class he came down to the gym and told me to come over to him. He told me that i wasn't allowed to do that and made a big deal and lectured me about it. He said "what if someone came down to the weight room looking for you?" and "your lucky i didn't write you up for skipping". As i walked away i was pretty pissed off and responded "how is that skipping if i am right down the hall?" He had no response because he does not know anything at all.
