uhh.. nope... even did that to the principal once..
it was a JC which treated everyone like adults... and we behaved
like so too.. if the class wasn't helping, we didn't
attend...
in the end, results were still pretty good 
in many ways, that JC taught us self-discipline... by letting us
learn responsibility for ourselves and not forcing their brand of
discipline down our throats... there were no disciplinary problems
at all
