A true story.

My phone bill was past due and I needed to change my service, so I had to
visit the local Bell of Pa. office. The line wasnt clearly formed, and
there was an old man with a cane nearby me. It was unclear as to who was
next.

When we got to the front of the line, the man gestured to me and said,
After you.

I smiled at him and said, No, please, after you. I have all day.

The he said, No. You go ahead. My doctor says I have at least six
months.
