I just have a little gremlin following me around and moving my stuff. I lay a screw driver on the edge of a table. I leave the room and, when I return, I can't find it. I search in and out of the room for a while and, finally, find it laying on the edge of the table. I am not kidding! I am quite certain this creature is real!
When I look for an item that I need really badly and can't find it, I give up and go for a new one. I tell my wife not to worry, I will trip over it when I get back. And, I usually do! I know that nasty little creature is here some where, if I could just find him.
