In the post office
The old man approached a young stranger in the post office and asked,
"Sir, would you address this postcard for me?"
The man gladly did so, and then offered to write a short note for the old fellow.
Finally the stranger asked, "Now, is there anything else I can do for you?" The old man thought a moment and said, "Yes, at the end could you add, Please excuse the sloppy handwriting."
