Ladies, I'm on the committee with two other moms. One of them was on my son's committee before, and she does everything herself without even asking – she just decides and buys things. I tell her, 'At least let us know or ask sometimes,' but she always asks everyone else, just not me, even though we have a decent relationship. Then, a friend of mine suggested New Year's gifts. I posted in the parents' group, and almost everyone agreed. But then she, and another mom (who I don't get along with very well), started complaining *after* everyone had already agreed and sent money. I told her, 'You told me yourself you were okay with it personally, but you're writing something different in the group...' Anyway, I said my piece and wrote that I'm quitting the committee. So, my question is: would you write to the teacher to have her removed from the committee, or would you just do nothing more?
