Dear Eric: We have a neighbor a few doors up who hates us. We don’t really know why, but he doesn’t want us to walk on “his” sidewalk. He considers that harassment by us – just us. We walk up and down the street for our health and pass his house six to 12 times a day. If he sees us through his window, or one of the more than 12 cameras on his house or next to the sidewalk (so he can eavesdrop), he runs out and turns on his sprinkler so that it sprays across the sidewalk, over his cars, and into the street.
