DD2 (in yr1) is friends with twins, one slightly more so than the other but we have had a few incidents in the past where dd2 has been upset by this friend. Anyhow, she told me this morning that she had been in the toilets on Thursday with said friend and my dd2 was still on the toilet when friend pushed hard against the door, opening it and banging dd2 on the nose and laughing about it. She then proceeded to do the same on Friday this time banging dd2 on the head. She denied that she had done anything and called dd2 a liar for saying she had, but dd2 says she saw her! So my dilemma is... I find this totally unacceptable behaviour, opening the door on someone on the toilet and hurting them, so am going to speak to teacher about it on Monday. BUT am becoming friendly with other girls mum and we are supposed to be going round after school on Thursday. Do I say anything to her or keep quiet (knowing I have spoken to school about her daughter)?
