Has anyone been stalked by a neighbor before?

My wife was stalked by the man next door when she was in high school and college. He couldn't spy on her bedroom since it was on the second floor, facing the street. He used binoculars to watch her sunbathe and waited at the window for us to come home on date night, watching us kiss and fondle in the driveway. She finally told her father, and he put a stop to it.
