A
man was very hungry, and went to buy cakes at a snack bar. When he finished a
cake, he found he hadn't had enough, and so ate a second one. He felt so hungry
that after eating six cakes in succession, he still hadn't satisfied his hunger.
Not till the seventh cake was eaten up, did he feel satisfied. Then, suddenly,
he had a feeling of regret.
"Ah, if I had known this before, I would have eaten the seventh cake first
and that would have been enough and there would not have been any need to eat
those six others."
