My dog, Gizmo, is convinced our house is magical. She's really pretty good at catching small bits of food such as popcorn tossed at her, but you have to get her attention so she can see the toss. However, if it manages to hit the floor, it didn't fall to the floor, it popped up out of the floor. When the floor pops, she simply has to watch that spot just in case it pops again. Sometimes it does you know, though never in the same spot. She has been known to stare at a certain part of the floor for hours or until she gets bored and falls asleep.
That's not all this house does. Every once in a while it eats me up and surely it spits me outside somewhere, though she has never been successful at finding me out there. I'll go back to the bedroom and disappear into the bed for a nap. She'll then pace the house looking for me in the bedroom and then asking to go outside and look there. Then she'll come back in and look in the bedroom again and then back out. Around and around, whining and worrying until I get up from my nap. Only then will she settle down.
There is of course no way to know what she's actually thinking. Sometimes I wish I could, especially at times like these.
