My DS is in year 2 at a big primary school. Two of the other mums are really chatty and friendly with my DS class teacher, making her laugh and always chatting to her lots before and after school. AIBU? Are they just being friendly? Is the teacher secretly just being polite but really would rather not talk to them? It is just really obvious it is these same mums every day. It just doesn't seem very professional or fair somehow, can't quite put my finger on it. All changing next year anyway with new teacher but wanted to hear some opinion or if others have experienced similar.
