I can add being bitten to the things done to me by students. I really thought I had had it all.
That being said however, today was the best day yet. Everyone ended on the highest behavior level, and we got to play outside. I might have even grown a microscopic filament of attachment to them (this has been slow going).
The biting only happened on the way out the door after school when a kid got bumped, got mad, destroyed the room, and then bit me when I tried to calm him down.
Eh. You win some, you lose some, you tie some.
