One afternoon, I was in the back yard 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."
