IABU - ignore. It’s minor. Things could be so much worse.
IANBU to resolve, and here’s my experience of resolving a similar problem.
Neighbour’s alarm goes off at 5am everyday. Regularly doesn’t turn it off so it vibrates/buzzes for an hour before automatically turning off. The noise vibrates through my wall waking and keeping me awake. I spoke to them a couple of months ago, and the alarm was turned off. They have now reverted back to leaving the alarm buzzing/vibrating.
They may be irritated with me. They park across my drive regularly and so regularly have to ask them to move. I know it’s a traffic offence to do this but don’t want to exasperate a easily managed problem.
I would really appreciate suggestions on how I can address their low level CFery amicably.
