Nap Time?

An older, tired-looking dog wandered into my yard.
I could tell from his collar and well-fed belly that
he had a home and was well taken care of.

He calmly came over to me, I gave him a few pats
on his head; he then 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, greeted me in my yard,
walked inside and resumed his spot in the hall and
again slept for about an hour. This continued off and
on for several weeks.

Curious I pinned a note to his collar: 'I would like to
find out who the owner of this wonderful sweet dog is
and ask if you are aware that almost every afternoon
your dog 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
6 children, 2 under the age of 3 - he's trying to catch
up on his sleep. Can I come with him tomorrow?'
