The Greedy Mouse
 

A greedy mouse saw a basket full of corn. He wanted to eat it. So he made a small hole in the basket. He squeezed in through the hole. He ate a lot of com. He felt full. He was very happy.

He wanted to come out, so he tried again. But it was no use. The mouse started crying a rabbit was passing by. It heard the mouse's cry and asked, "Why are you crying my friend ?". The mouse explained, " I made a small hole and came into the basket. Now I am not able to get out through that hole: The rabbit said," It is because you ate too much. Wait until your belly shrinks". The rabbit laughed and went away.

The mouse fell a sleep in the basket. Next morning his belly had shrunk. But the mouse wanted to eat some corn. So he ate and ate. His belly was full once again. He thought, “Oh ! Now I will go out tomorrow”. The cat was the next passer-by. He smelt the mouse in the basket. He lifted its lid and ate.
