We live next to school playing fields, in an otherwise purely residential area. Some sports club plays there late every Monday, lots of whistle blowing, they are still playing (9.37pm). For 10min after they finish there will be loud talking outside our house as the people leave. AIBU to think this is a tad too late for a regular event?! It stops me from going to sleep and I have to be up at 5.15am.
