LOL, you find good jokes.
One afternoon, I was in the backyard hanging the laundry when an old, tired-looking dog wandered into the yard. I could tell from his collar and well-fed belly that he had a home.
But when I walked into the house, he followed me, sauntered 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. He resumed his position in the hallway 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."
