Just for fun, I was suspended for having hair that was too long. I ignored the suspension, kept coming to school and threatened to cause all merry hell with the local press.
Incidentally, that might be a good idea for Trixie. Write a piece on how the school is putting the health of children at risk, maybe even get a local GP to sign it too and send it in with a PS advising that the local papers will receive a copy if the policy remains.
