Thanks, Neighbor Watching: You're right, of course.
Three years ago the neighbors literally stood by and watched while people ransacked my late parent's house, carrying all of my great grandparents heirlooms out to a large white moving-style truck, because they thought "perhaps the truck belongs to new owners." ----- never mind that the house has never been for sale.
TPD would rather have been called so they could have saved me the heartache of loosing my family's belongings by checking out why there were movers there. Every time I remember the neighbor lady telling me , "Well, we didn't know . . ." I want to vomit. TPD would not be angry if it turns out that everything is legit. TPD WANTS you to call and let them investigate.
