Irrefutable logic is a supreme irritant for physics teachers - particularly the histrionic shouting type who never actually carry out a threat. Notably, Mr Linton.
Spotting me chatting in the corridor with a friend, who he'd also just chucked out of the class, he shouted 'Alexander, I thought I told you to stand outside the staff room! Why are you in the corridor?'
My response? 'Sir - I'm not standing INSIDE the staff room, and since I AM standing, I can only conclude that I must be standing OUTSIDE the staff room.'
Impressed with my scientific reasoning, he screamed in my face for a few moments before meandering away, muttering threats.
