Write an umbrella as a joke of life.

In this rainy season, a child always takes an umbrella as his life. Once at school, it suddenly rained heavily and the child didn't bring an umbrella. Because of the power failure, he could only write and say that going home killed him, but I lost my life. If there is life at home, bring my life here quickly. If there is no life, then help me buy it. If it comes late, I will lose my life and go home.
