A funny story about an old dog

Once an old tired dog came into my yard. Judging by the collar and fat belly, he had a home and was well cared for. The dog calmly approached me, and I patted him on the back of the neck. He followed me and entered the house. Slowly crossed the hallway, curled up in a ball in the corner of the living room and fell asleep. An hour later he got up and went to the door. I released it.

The next day he was again in my yard, "greeted" me, went into the house again, took the same corner in the living room and again slept for about an hour. This went on for several weeks in a row. I got curious, and I pinned a note to his collar: "I would like to know who is the owner of this wonderful cute dog, and did you know that almost every day he comes to my house to sleep?"

The next day the dog came with another note, pinned to the collar: “He lives in a house with six children, and two of them are not even three years old. He's just trying to get enough sleep. Can I come with him tomorrow too?
