You can't change the weather, but you can change your mood. Please help me make up a story suitable for middle school students to speak and read.

An old couple has two sons. The boss sells umbrellas, and the second sells noodles. Whenever it rains, the old lady will sigh: "Hey! The second son's face is not easy to sell. " Every sunny day, the old lady will sigh: "Hey! The umbrella of the eldest son is not easy to sell. He was always unhappy and died young, but the old man was not. On a sunny day, he would say, "Haha, the noodles of the second son sell well. "When it rains, the old man will say happily," Haha, the umbrella of the eldest son sells well. "As a result, it is conceivable that the old man is still very healthy at the age of 80. You can't change the weather, but you can change your mood, although people need to be happy.
