A man writing at the post office desk was approached by an older fellow with a post card in his hand. The old man said: “Sir, I’m sorry to bother you but could you address this post card 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 hand-writing’.”
