Open closed heart

The open and closed heart has failed everybody, but people's attitudes toward failure are completely different. The successful sun can dispel the darkness of failure.
There are two brothers, who are only four or five years old. Because the windows of the bedroom are closed all day, the house is very dark. When they see the bright sunshine outside, they are very envious. The brothers discussed and said: "We can sweep the outside sun together." So the two brothers took the broom and the hoe and went to the balcony to sweep the sun. When they moved the raft into the room, the sunlight inside was gone. This has been repeated many times and again, and there is still no sunshine in the house. The busy mother in the kitchen saw their strange move and asked, "What are you doing?" They replied: "The room is too dark, we have to sweep the sun in." Mom laughed: "Just open the window, the sun Naturally come in, why bother to sweep it?"
