My son has just started school and I've said hello/goodbye to the other mums at the school gates but I haven't made conversation more than that. I've heard about school mum cliques and drama on here and I'm not interested. I'm just there to drop my kid off. We've had a note in his bag that some mums have started a group chat on WhatsApp and to text one of them to join and I didn't do anything with it. My husband has found it and is saying I should join it for our sons sake, get friendly with his potential new friends mums, be invited to things. I don't really know what to do now but I feel like I don't want to be in it, is that wrong of me? Or am I right to avoid and just keep a bit distant?
