My mother-in-law sent this to me. She thought I might find it funny, and I did. Funny enough to post on my blog:

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?'
