BT, my dh ran into someone a bit like your neighbors a while back. DH was redoing a house for my cousin who is selling the property. After completing the work on the house, he cleaned the yards very good. One neighbor has been very good about cutting the front yard when dh was working so hard, so he cut their yard, then the lady across the street had been very nice and brought him iced tea and complemented the work he was doing. DH decided to cut her yard too, then he cut the front yard of the neighbor on the opposite side of the house. Just as he was finishing, the neighbor where he was cutting drove up and said - "Wait a minute and I will move the stuff in the backyard so you can do that" WHAT???? DH said, No, I saved that for you.
