Long ago, an old farmer lived on a few cows and sheep.
One day, a lion ran into the farmer's pen. He wondered this was a gift from the heaven. He thought, 'If the lion is sold, I will probably make some money.'
While happily calculating, the farmer shut all the gates.
Since the lion could not come out, it ate up all the cows and sheep in the pen.
At this time, only did the farmer begin to worry about himself. He was afraid he might be the lion's next meal. For the sake of safety, the farmer could only set the lion free.
The farmer vented his grievances to his friend. His friend did not console but lecture him, ' You should reap what you sow! Why did you lock the lion in your own yard?'
