An old, tired-looking dog wandered into my garden one afternoon. I could tell from his collar and well-fed belly that he was well looked after. I gave him a few pats on the head and he followed me into my house, slowly walked down the hall, curled up in the corner, and fell asleep. An hour later, he went to the door and I let him out.

The next day he was back. He resumed his spot in the hall and again slept for about an hour. This continued for several weeks.

Curious, I pinned a note to his collar: “I’d like to find out who the owner of this wonderful dog is, and ask if you’re aware that almost every afternoon he comes to my house for a nap.”

The next day he arrived for his nap with a different note pinned to his collar.

“He lives in a home with six children,” it read.

“Two are under the age of three and he’s trying to catch up on his sleep. Can I come with him tomorrow?”
