The Postcard

A man writing at the post office desk was approached by an older fellow with a postcard in his hand. The old man said, "Sir, I'm sorry to bother you, but could you address this postcard for me? My arthritis is acting up today and I can't even hold a pen."

"Certainly sir," said the younger man, "I'd be glad to."

He wrote out the address and also agreed to write a short message and sign the card for the man.

Finally, the younger man asked, "Now, is there anything else I can do for you"?

The old fellow thought about it for a moment and said, "Yes, at the end could you just add, 'P.S.: Please excuse the sloppy handwriting'"?
