A friend from DS's class is having a birthday party, I know about it as most of the other parents have mentioned it, DS hasn't received an invite though
He is a friend of the little boy and child's mum has seen them greeting each other in the morning so is aware of him
I know not all the children are attending as there are several new children but DS started with this child so they have been friends for a while
AIBU to feel a bit upset?
