A boy is allowed by his mother to put his hand in a jar and take the peanuts inside.
And the boy put his hand in the jar to pick up the nuts, but because the boy took the bean with a very large grasp, he could not pull his hand out, and there he stood up, unwilling to release a bean of nuts from his grip because he wants to take it all at once.
Out of curiosity and disappointment she started to cry. "My son," said his mother, "take the beans half-handed, so you'll be more comfortable removing your hands from the jar, and you'll probably have more nuts if you take them over and over again." Do not do too much at once.
