years ago one day i was leaving for work. walking away from my house when a car came behind me very slowly. i turned and waved at my empty house and kept walking. the car went away. i always thought they might be casing homes and seeing me leave, they might have thought about going into my home. but not with the invisible person there i waved to.
these days they just knock and break in.scary world.
when people come to the door if i must, i mention my husband or son. even if i'm alone!
