I realise it's new year's Eve but the next door neighbours have gone away leaving their teenage son at home and he is blaring music as per usual when they go away, AIBU to consider knocking on their door and ask him to turn it down? It's waking up my toddler who normally sleeps through anything. He never answers the bloody door even for deliveries so I doubt I will even get to talk to him but hopefully me knocking will be enough of a hint.
