We live in an area with a fairly high turnover of families. People come and go all the time. Children join the school and leave.
I have a friend who, every year, throws a party for her boys (twins in the same year) and invites all the children who have been in the school together since reception.
My daughter isn't invited because we didn't arrive until a year after reception. I am mildly sour grapes about it. I'm not exactly sure why it irks me because I'm honestly not bothered when my children aren't invited to parties. You can't go to everything, and we certainly don't invite everyone we know to everything.
But... I don't know, something about it just seems a bit mean spirited to me. Am I totally out of my tree?
