I've today received a birthday invite over WhatsApp for my 10 year old daughter. I know the Mum of the birthday girl well enough to stop for a chat but not good friends. I've found out from a mutual friend that this party has been arranged weeks ago with a WhatsApp group and everything. One of the girls dropped out as they have something else on and that's when I got the message inviting my DD! AIBU to tell her to stick it as my daughter is clearly an afterthought? DD isn't fussed about going, she likes the girl well enough but not that friendly at school!
