A few houses down from mine there's a sweet old man who lives with his son and daughter-in-law. Every day I walk my dog past his house and he comes out and talks to me. I'm pretty sure he has no idea what my name is. The truth is, I have no clue what his name is either. I just refer to him as the old man.
In spite of our lack of familiarity, we have a nice chat every morning. His son (who is closer to my father in age than he is to me) and I like to chat about politics regularly. He and I are both Romney fans. The old man voted for Obama.
On occasion the old man will ask me for help with something if no one else is at home with him. A few days ago he came out of the house in a huff, holding a letter. His son was getting in the car to leave and warned me his dad was in a mood because he just got a letter about his Social Security. After the son left, the old man and I had a chat.
