DS is friends with a group of boys who have known each other since nursery but DS has been mates with them all through school so far.
So we go into another year at primary and one of the mothers still goes on about DS being an imposter into the group, never invites him to anything, purposefully talks about how they have all been doing stuff together all summer in front of DS - she even started showing DS pics of a day trip out on her phone that they had all done.
Its really horrible and the same every year- none of the other kids parents are like this and DS has seen others seperately over the summer.
Aibu to say something? DS never says anything but I can see it hurts his feelings and makes him feel left out.
