Dog tired story

An old, tired-looking dog wandered into the yard.  I could tell from his collar and well-fed belly that he had a home.  He followed me into the house, down the hall, and fell asleep in a corner.  An hour later, he went to the door, and I let him out.

The next day he was back, resumed his position in the hall, and slept for an hour.  This continued for several weeks.

Curious, I pinned a note to his collar: “Every afternoon your dog comes to my house for a nap.”

The next day he arrived with a different note pinned to his collar: “He lives in a home with ten children — he’s trying to catch up on his sleep.  Can I come with him tomorrow?”
