I've posted before about our recent dispute with the neighbours next door who have been very friendly up to this point, as have we. The disagreement we had was regarding them putting their food waste in our recycling bin resulting in it not being collected. We mainly keep ourselves to ourselves in the street as it's my parents house and we don't want to cause bother when we're not going to be here forever. We politely asked them not to do this in future and were met with a less than desirable response. I have not spoken to them personally since, neither has my DP but my mum has. They dart into their house if they see us coming/turn the other way etc I expect out of embarrassment for their reaction. The noise out of their house (music/partying/diy general banging and crashing) is unbearable sometimes and has got worse since we mentioned about the bin. They know we have a young toddler and often are very noisy at night, sometimes after 11pm. I haven't complained in the past but I definitely will after today as I've just had a knock on the door from a council officer to tell me a neighbour has made a complaint about us putting our rubbish in their bin and leaving bin bags lying around, neither of which we do! The officer then asked if I would keep my bin in our back garden in future, which it always is except for one morning of the week for it to be collected. As it's untrue to me it's obviously malicious and therefore it must be them. I am livid, AIBU and WWYD?
