The story is told of two polite people who were having dinner together. On the table there was a dish with one big piece of fish and one small  piece of fish.

They politely said to each other: "You may choose first."

"No, you may choose first."

This went on for a while. Then the first person said, "OK, I'll take  first." And he took the BIG piece of fish.

The second person said, "Why did you take the big piece? That's not polite!"

The first person said, "Which piece would *you* have taken?"

The second person replied, "Why, I would have taken the SMALL piece, of course."

The first person said, "Well, that's what you have now!"
