I don't know if returning the cards is bad. If she sends your teenage kid a card, it seems like that is between her and the kid. I probably wouldn't get involved in the cards, but I sure wouldn't send any or remind anyone else in the house to send any. The adult women in the house tend to be the people to send cards, so I'm guessing that if you don't send her a Christmas or birthday card, no one else in your house is either. That seems like enough of a sting.

I can see reasons for returning the cards as well, especially if she has been told not to send any. That is a tough one.

I hope she doesn't live near you. She sounds pretty horrible.
