Having just read the thread about awful things teachers said and did to us at school got me thinking about some of the ways children made teachers' lives a misery.
My uncle and his classmates would get up on their desks before a certain nervous young teacher came in and get all the ceiling lights swaying in unison. They'd then stand politely behind their desks as the teacher entered: all swaying together in the opposite direction to the lights. The poor teacher didn't last a term
Anger management!!! Help needed.
