Neighbour plays in a band. When DD was about 5 weeks I had a meltdown at them for playing very loudly in the middle of the afternoon - drum kit, keyboard and guitars on amplifiers etc. Took 3 goes to get them to hear me banging on the door, and he said "Oh sorry, we didn't think anyone would be disturbed" And said they wouldn't do it again, in the manner of a chastised schoolboy.
Today they're going for it again. Now I don't object to the band practice per se, as obviously they've been trying to do it somewhere else for the last month, but AIBU to want some warning so I could at least have made plans to go somewhere with DD rather than have her woken up and unable to get back to sleep? It's not as if they're feckless teenagers, he's in his 40s and they have a 5 year old kid themselves so know how hard it can be to get them to nap during the day.
