I live in a terraced house, going round a block, so all our back gardens form one long rectangle. Someone has recently got themselves or their dc a drum kit, kept in a back room upstairs - they practice a fair bit and seemingly always with the window open.
It's finally a nice (well, warm and not raining) day and I'd like to sit in my garden to enjoy it without the drumming background noise at least being muffled by a window.
AIBU to think this is a bit off and to go round, if I can identify the house, and ask them to shut their window?
