The train started moving. It was packed with people of all ages. Most of them were working men and women and young college boys and girls. Near the window sat an old man with his son, who looked about thirty years old.
As the train moved, the son was filled with joy because he was very excited at the scenery outside. He said in a high voice, “See Dad, the green trees and the scenery are very beautiful!” It made the other people feel very strange. Everyone started talking in a low voice about the old man’s son. Suddenly, it started raining. Raindrops fell on the travelers through the open window. Seeing the rain, the old man’s son said happily, “See Dad, how beautiful the rain is!” Hearing these words, a young lady became angry with the man, as the raindrops were dropping on her new clothes. She couldn’t help shouting at the noisy son and his father.
“Can’t you see it is raining? You! Old man! If your son is not feeling well, get him to a mental hospital quickly and please don’t disturb us any more!” The old man’s face turned slightly red and then in a low voice, he replied, “We are on the way back from hospital. He was blind at birth. Only last week he can see again. The rain and the nature are new to him. Please forgive him.” All the other people became quiet.

Everyone worries. But how do you deal with your worries? Whether your worries are big or small, you can take these three steps to do with your worries:
1. Try to find out what you’re worded about
Sometimes, you will know what you’re worried about. Other times, you might not. Try to find it out first; if you can’t, you can ask for help.
2. Think of ways to make it better
There is always something you can do to help you feel less worded. Sitting there worrying is no fun and it won’t solve your problem.
Grades at school are often top worries for kids. If you’re worded about grades, ask yourself these questions:
★ Why are grades important? What do grades mean to me?
★ How do I get ready for class? Do I go over my notes even when there isn’t a test?
★Do I have a good place to do my homework?
★ Have I tried different ways of studying?
If your worry is about a fight you had with a friend, you might write down all the things you could do: write a note to him or her, invite him or her to a basketball game, say sorry to him or her, etc. Once you have a list of things you could do, you can choose the one that gets your friend back.
3. Ask for help
When you’re worried, it can help to find someone to talk to. You can ask your parents, friends, or teachers for help.
