My son is 12, he is yr 7 of secondary school. For as long as I can remember he hasn’t been invited to many parties, maybe a handful since he was a baby. He had a gaming party recently, 6 boys came. One of them told me it was also his Birthday & he was having a bowling/darts party, no invite in return. Equally the 6 boys that came to his Birthday also came last year & only one of them invited my son to his Birthday. He is lovely boy, not overly outgoing or confident, he isn’t sporty so we don’t see parents at clubs etc but I make the effort to always say hello & be polite. Just wish he would be invited & not left out!
