Use

U - Use is a letter in Rolypolys no Nanakorobi Yaoki.

Plot

George is shown setting up a picnic. He then sits down and pours himself a mug of milk which he proceeds to dip his whole head into, spilling the milk. After doing it once more he runs out of milk. The scene ends with George staring into the sunset.

Moral

"It's no use crying over spilt milk."

Explanation

"Literally: Spilt water never returns to the bowl.

What's done is done, and cannot be undone; so there is no use feeling regret or remorse. There is such a finality in this, don't you think? But isn't this how things really are? Haven't you found that it is simply impossible to take back a comment that you unwisely made, or reverse a decision that shouldn't have been made? George, for one, sure wishes he was more careful in drinking his milk. That's right, we must think before we act - not after, when it's too late."
