I would have called. Better safe than sorry and I never want to be saying, "I never thought it would happen to me," after the fact.
WE just filed a report last night. The Hubster found someone watching the house, lights off Friday evening. Long story but we know who it is.
He just happened to be coming home and in a borrowed car, so he drove past them and the house and around to find them slowly driving away watching the house.
Makes you wonder how many nights they've been out there that we don't know about.
