I work from home (always, not just a few days a week or because of Covid) and my office opens onto my garden. The section of garden it opens onto is about three metres or so from the boundary fence that separates our garden from our neighbours'.
This neighbour (who we don't have the best relationship with for a number of reasons - but I should say he's attended anger management courses in the past and other neighbours warned us about him in the past) built some kind of permanent gazebo attached to the fence (which also takes light away from our living room but it's been there for longer than we could now report it so it's there to stay) and given they are a retired couple, they spend most of their days sitting there, smoking and playing music. When their grandchildren come over to use the temporary pool, it's constant shrieking (and throwing stuff into our garden!).
We usually don't say anything but today they have started playing some sort of techno music so loud that the people on my conf calls can hear it through my laptop microphone (I have the door open because of the heat).
I tried to call out 'hello? hello?' in a 'friendly voice' but nobody answered. So they either left the music going and left the garden, or just don't care at all. I am getting more and more annoyed at the fact that I might end up having to close the door because of their music, especially in this heat.
AIBU to think they should be more considerate? That when they built that structure attached to the boundary fence they should have realised they couldn't use it as if it where further from our garden?
And, more importantly, how can I get them to stop playing loud music? Thank you!
