The problem with annoying neighbours is that they lack the common decency to comply. By definition, if they had the required decency then they wouldn't become annoying in the first place.
The general advice always seems to be to talk to your neighbour about the problem but, in my experience, this never works and is more likely to aggravate an already testy relationship.
Thus far, until 'being annoying' becomes an acceptable defence for murder, the only strategy that works 100% is to move.
Repeatedly. It's a weird power dynamic that neighbors have. He's not a rude person, but he just doesn't "get it." I asked him to run his blower any time except 9-12 and 1-5, but that worked for like 2 days.
