Off Topic What would you do?

[emorymom]

Here's a hypothetical example of a reason NOT to exclude one and only one team child from your child's birthday party: you don't like that the eight year old on your daughter's level talks about the Percy Jackson books. You think perhaps that child is headed for eternal damnation.

I personally would not get into inviting part of training group without inviting all. I don't really care if my kid WANTS to do that; he or she can live with the many wonderful options that involve either inviting all or none.
