Ummm, one instance... An angry preteen punched a co-worker for opening a window.

I have to explain this here because in general we do not punch people. We were sick with a fever (a trigger for self-protection - we were not looked after when sick, so generally get very protective of selves when ill) and it was the middle of winter... douchebag co-worker insisted on throwing the window wide open in freezing weather despite us asking him not to because we were unwell; preteen leaps to the fore and whops him one.

Yeaaaah, not cool.

(hmmm, so maybe preteen wholloped a few other adults in her time too. A tyrant of a school principal springs to mind... )

How do you protect yourself?
