Those parents are a bunch of stupid selfish morons! Almost no-one is so allergic to a small amount of dog dander that it should affect schoolwork, and if they are then that is a serious medical situation that would be solved by moving the allergic child to another class.

A friend of mine has Cerebral Palsy, and if anyone ever treated him that badly I would rip them to shreds. The poor boy has a hard enough time already, I wish there was a way that all of those parents could be in his shoes for a week.
