The dog follows me into the house, goes down the hall, jumps on the couch, gets comfortable and falls asleep. Thinking this is rather odd, I let him sleep. After about an hour the dog wakes up, walks to the door and I let him out. The old dog wags his tale and leaves.
The next day, the dog comes back and scratches at the door.
Again, I open the door, and the dog comes in, goes down the hall, jumps on the couch, gets comfortable and falls asleep again. Again, I let him sleep.
After about an hour the dog wakes up, walks to the door and I let him out. The dog wags his tale and leaves.
This goes on for days. By now, I am really really getting curious, and I pin a note on the dog's collar: "Your dog has been taking a nap at my house every day."
The next day the dog arrives with another note pinned to his collar:
"He lives in a home with four children -- he's trying to catch up on his sleep. Can I come with him tomorrow?'
