Stubborn dog and troubled owner

he went to the door, and I let him out.
The next day he was back, resumed his
position on the couch 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 four children —
he’s trying to catch up on his sleep. Can I come with him tomorrow?”
