Students who arrive at my lesson with a HUGE bag but no pen annoy me. Yesterday, I was helping in a maths lesson. None of the students had a pen, pencil or ruler!
Shop assistants who carry on a conversation whilst serving annoy me too.
People who park on pavements and completely block the path make me want to smash their cars to pieces.
Cold callers who phone me at 6.30pm and ask me personal questions about my home sometimes get an ear bashing if I'm in the right mood.
People who put Kleeneasy catalogues through my door but never collect them from the doorstep get on my nerves.
