Our neighbours have just spend a fortune doing up their garden and have put in a swimming pool. Every sunny day they are now outside using the pool - not a problem. The problem is the top volume music they play every time. Our garden has gone from being peaceful to really stressful.
I do not want to fall out with them, so how do I say politely that loud music every time they use the pool is unreasonable to the houses around them who also want to enjoy their gardens.
