Just feel a bit sad for him. He is quite shy and neurodiverse and won't be staying in at sixth form. He has school friends who are going and have bought ticket which wasn't cheap but now he has said that he's not going. DH says that I should leave him be and not force it and he will need to pay us back for the ticket but feel sad as think he's probably enjoy it when he's there and that it's a rite of passage. However we didn't do it as teenagers. Why do I feel sad? And should I encourage him to go?
