i don't agree with her carrying on, certainly, but you and others here act like the kid needed the exercise, shouldn't be on a bus anyway etc. and that is not remotely the point. my kids are all in private school and i wouldn't take this crap from any of the 3 schools in question. maybe it a byproduct of our paying tuition, but when we entrust our kids to someone, mistakes are NOT acceptable.
It must be hard for you, being perfect in an imperfect world.
