...when your heart aches for your child after she tells you, with tears in her eyes, that today her teacher told her to just be quiet and go sit down after she asked the teacher why one of her problems on her worksheet was checked wrong.

I guess self-advocating only works when the adult educator in the situation gives a hoot and I bet DD won't do that again any time soon. Thanks a lot "educator of the year" *sarcasm!*

FWIW - DD did this at the appropriate time (wasn't interrupting the teacher or anything) and I looked at the problem myself and it was a correct answer.
