I'm not sure where to post this. AIBU seems too harsh and I know there's fault in both sides so don't want to get bashed. Anyway...
We live on a development that's relatively new and everyone has moved in over the last two years or less. We have been here nearly a year and I get on well with most of the neighbours (some just to say hi to and others to actually have a good chat). Whenever anyone has moved in after us nearby I've always sent a card and introduced myself to welcome them to the area. However my husband is the opposite to me. He'll be civil and polite to some people but he has a one chance rule and generally has a dislike of everyone round here.
The people out the back from us moved in a few months ago and they have not made themselves friendly to others. Every weekend (and some week nights) they have parties till 2/3am with music, lights, shouting and hollering. The majority of people round here have very small children and babies and it's summer. It took me two and a half hours to get my son to bed last night because it was too hot but I couldn't open the window because if the noise. I'm now considering moving him into his own room ASAP so he's on the other side of the house and it might be less noisy. However it's all the houses they are bothering.
Tonight however my husband decided to "talk" loudly to our son about how inconsiderate people are when they stand against our fence shouting at 1am and how it's not nice to have to pick up the or empty cans and bottles in a morning because they've made it into our grass. We have had to go out before now and clear up the garden before our son could play outside (although we get slugs too so it's sometimes an issue then anyway). The problem is the people heard him and started kicking off. They've since increased the volume and set off fireworks. I know being passive aggressive is wrong and he shouldn't have but it's frustrating.
I don't know what to do though. If I don't side with my husband he'll be annoyed that I'm not supporting him; I do support him but I don't think being passive aggressive is the answer. If I go over and speak to them they'll tell me to sod off. People ha e already asked them to keep it down and they got abuse shouted back at them. What can I do?
