Grandpa called me at work to tell me that someone had broken into the house and stolen the dog.  He was certain.  I didn't even try to help him reason through it.  I just came home.

The dog was in my room, like she usually is.   Her favorite sleeping spot is under my bed.  Grandpa had closed my door, so she couldn't get out when he called her.  He doesn't usually do that.  When I told him that she had been under my bed, he said that he'd looked under my bed; that he'd gotten down on his hands and knees and looked.  I know that isn't true, mostly because grandpa can't really get down on his hands and knees and still be able to get up without some assistance.  Of course, if he had looked, he'd have found the dog.
