One day, two mice fall in a drum of milk. First they drink some milk and try to come out from the drum. But it is not easy to escape from the drum. They are trying a lot to jump out but could not succeed. One mouse thought that his life will end there only because there is no escape and so he started drink milk as much he can. As the weight increases the mouse easily drowned in milk and died. But the other mouse started moving around the drum and drinks a little milk to get his energy for moving. Moving, moving and moving, finally he prepared butter from the milk and jumps out from the drum with some butter.
This is the life.
