     A mouse looked through a hole in the wall to see the farmer and his wife opening a package; what food

could it contain? He was astonished to discover that it was a mouse trap!

     Running to the farmyard, the mouse shouted, warning everyone, "There is a mouse trap in the house,

there is a mouse trap in the house." The chicken, with her head high, glared at the mouse and said, "Shut up.

Little Ugly. This is a great concern to you, but it has nothing to do with me:I can't be troubled by it."

     The mouse turned to the pig and told him."There is a mouse trap in the house." "I am so sorry, Mr

Mouse," said the pig sympathetically, "but there is nothing I can do about it but pray；you are always in my

prayers."

     The mouse turned to the cow, who said,"A mouse trap, am I in great danger, huh?"

     Now the mouse had to face the farmer's mouse trap alone.

     That very night a sound was heard through the house, like that of a mouse trap catching its prey. The

farmer' wife rushed to see what was caught. In the darkness, she did not see it was a big poisonous snake

whose tail the trap had caught. The snake bit the farmer's wife. The farmer rushed her to the hospital. She

rerturned home with a fever. It is said that drinking fresh chicken soup will help treat fever, so the farmer took

his sharp knife to the farmyard for the soup's main ingredient. His wife's sickness continued, so friends and

neighbors came to sit with her around the clock. To feed them, the farmer killed the pig. The farmer's wife did

not get well, in fact, she died, and so many people came for her funeral. The farmer had the cow killed to

provide for all of them to eat.

     So next time when someone is facing a problem, don't say that it has nothing to do with you.
