Tired Dog Tired Mom

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 promptly 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 a couple of weeks.

Curious, I pinned a note to his collar one day. It read:

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 nine children (aged 8 months to 10 years) - he's trying to catch up on his sleep. Do you think it would it be okay if I came with him tomorrow?
