Hello, was looking for some advice on a tricky situation ...
My DD has just started primary school and has been loving it! However the past week my DD has been coming home saying that another child has been hitting her. A few days ago she said it so loudly that said childs mum heard it and that night I had her partner knock on my door telling me that since starting my DD had been hitting their daughter and that they've been talking to the teacher about it - nobody told me this?! I responded nicely and explained that my daughter has been saying the same about their child but I will talk to my DD about playing nicely and speak to the teacher to see what's been going on; ofcourse I'm not there and I dont know the full story so cant go telling my dd off for something she may not have done! When my neighbour spoke to me he seemed like he wanted me to do something about it there and then, like scream at her? and left red faced and annoyed with my response to the situation and hearing his wife screaming at him, telling him he should have done/said so and so 
Anyway, I spoke to the teacher the next morning and she explained that she has been keeping an eye on them and as far as she has seen, they havent really been playing together? My DD often talks about other kids shes been playing with, so this is compeltely out of the blue to me.
Our neighbours never seemed to have liked us for some strange reason, we have always been civil with them but now I dont know what to think or do?
I'll be honest they have not been the best neighbours, they argue everyday and night, slamming doors and banging on walls out of anger and screaming at their dd, lound enough that the entire street can hear them! Theres been numerous times when the arguments are so bad they have woken my kids up in the night, especially my 8mth old... but I dont want to come across as snobby, I'm just giving an idea of what these people are like! Of course we all have arguments now and then with our partners but surely not every single day/night since the day he moved back in with her?
She always ignores me when I say hello and he just stares and tries his best to ignore me also, but yesterday we ended up walking behind him and his dd and, as kids do, they were talking to each other, I was being and nice and so was he?
I was just hoping for some advice on what to do, I feel confused and really dont know what I'm supposed to do? Theres definitely a lack of communication somewhere but I dont want to keep bringing it up and make things worst? I'm so confused... TIA x
