I take a girl in DD year to an after school club. The girls are not best buddies but definitely friendly. The mother of the girl is very vocal in not inviting my DD to birthday and a xmas party. I have just found out she invited a little girl to her party that left the school two years ago and haven't seen each other since. I just can't see the point of continuing to do this taking/dropping if she obviously doesn't think enough of DD to invite her. I feel a bit used to be honest and a bit hurt. What would you do?
