It's been going on for MONTHS, and you haven't actually bothered to say a thing to him about it? Tell him to knock it off and be done with it. it really is that simple.
The house will be mostly unoccupied during summer, he'll get plenty of time to camouflage my car while we're away. Nothing new will happen until September anyway...
Naw, the leaves are so "dense" that they usually stay where they fall, on our land, they cannot really fly.
If they went in his direction they would be blocked by his gate, and remain on public ground.
What really bugs me it that this guy usually behaves like a nice and almost cheerful individual, that is waving to say good morning, have a bit of smalltalk if we cross paths, he even helped me maneuver my car out by checking for traffic on our narrow street. Yet he will still go out every night, grab a few leaves and stuck them in the wipes.
I don't know if he's intentionally sending mixed messages to further confuse the situation, if he's just plain nutjob on this particular issue without realizing it, or if he's really trying to make a point.
