I know you were being a little facetious, but I think it's dumb when people complain about getting in trouble for not following rules they said they'd follow. BYU is what it is, and you knew that when you applied. No need to complain about having to follow the rules you said you'd follow, right?
I'm in the Air Force. When I signed my contract, I knew I would have to shave before going on base. If I didn't shave, and someone yelled at me for it, I would have no one to blame but myself.
