Crazy Ass Neighbor

I have a crazy ass neighbor.  I enjoy the free mowing of the yard, since I didn't ask him to do that, the free trimming of my overgrown bushes, since I didn't ask him to do that, but trimming my overgrown trees in my backyard that go over your fence by approximately 1 inch and then throwing all the cuttings into my back yard?  Not enjoying that.  Freak.
