I go to a family's home to teach piano to their two teens girls. What I have noticed is that the guy across the street seems to have a compulsion to drive his truck in and out of the driveway. I asked one the girls - She says he does this all the time. Sometimes he waits for a long time, just sitting there in the street (in the truck) and waits, then goes around the block and re-parks. I HAVE OCD and I really think this guy has it too. I just hope he gets some help. I hope he finds out he has OCD.
