We all know a story similar to this： Two Men and a Bear. In the forest, when a bear attacked them, the thinner man quickly climbed up to the top of a tree and forgot his promise to the fatter guy, who could not climb the tree, about helping each other when in danger. Luckily, the fatter man saved himself. The fatter mat was very disappointed, and when they got together again, he said to the thinner man, You are not my real friend. Only a friend in need is a friend indeed. This is a very familiar story. It illustrates to us what a friend should be like. It is, however, just a story.
I would like to tell you something about myself, my true feelings. When I was in Senior One, I had great difficulty in learning science subjects. I was unable to understand the teacher and i could not do the exercises or the homework. I believed that I was stupid and could not learn anything. The sky was gray and the grass was yellow those days. Everything was a mess in my brain. My classmate, a good student, whom I only considered as one of the classmates before, came to me with a smile.
She told me that if I needed help, she would like to help me. As she was also very busy with her studies,I asked myself, Could she help me? Several days later, I knew the answer. Yes, she could. She did as much as she could. She made time every day to help me solve the problems and showed me many good ways to study science. Her patience and earnest nature touched me deeply. I worked very hard and my progress was reflected in my examination result. I appreciated her help very much and wanted to thank her. When I looked at her, once again she smiled at me with an encouraging and congratulatory look. At that moment I understood that a true friend should be like this.
And I have another close friend, we grew up together , she’s a person who is sensitive about my feelings ,and she is very supportive and always listens to my problems. When I sad , she will be the first time to my sad and looked at me cry but don’t say a word , and then take me to eat delicious .sometimes I’ll say some other people don’t understand sentence , but she knows.
So I think they are not the same .
Nowadays, it seems that there are many ways of expressing friendship. Our lives are generally better. People now have more time to consider and be more concerned about their lives. Money, which is considered by many to be of prime importance, makes it difficult to find true friendship. Is friendship only greeting each other on meeting? Is friendship only drinking and eating together? Is friendship only lending money to each other? No, a friend Should be a person you trust and understand. A friend should be a person who tastes happiness and bitterness with you. A friend should be a person who can give you confidence and encouragement.
Though everything has changed, and friendship has scores of definitions, I still believe, and I will believe forever that A Friend in Need is a Friend Indeed.

We all know the story about two men and a bear. The story goes like this:A thin man and a fat man were close friends.They promised to help each other when in trouble.One day,they were walking in a forest when a bear suddenly appeared,the thin man quickly climbed up to the top of a tree without thinking about the fat guy who was too fat to climb the tree. Luckily,the fat man saved himself. However,the fat man was very disappointed at their friendship. When they met again,he said to the thin man,You are not my real friend. Only a friend in need is a friend indeed.
This story is very familiar to us. It tells us what a friend should be like. However,it is just a story.
I would like to tell you something about myself.It's my true experience. When I was in Senior One, I had much difficulty in learning science subjects. I was unable to understand the teacher and I could not do the exercises or the homework. I believed that I was stupid that I could not learn anything. Everything was colorless those days. Everything was in a mess.One of my classmates, a top student, whom I was not very familiar with , came to me with a smile.
She told me that if I needed help,she would like to help me. As she was also very busy with her studies,I asked myself, Couldshe help me? Several days later, I knew the answer. Yes,she could. She did as much as she could. She made time every day to help me solve the problems and showed me many good ways to study science. Her patience and earnest nature touched me deeply. I worked very hard and made a big progress in my examination . I appreciated her help very much and wanted to thank her. When I looked at her,once again she smiled at me with an encouraging and congratulatory look. At that moment I understood that a true friend should be like this.
And I have another close friend, we grew up together , she’s a person who cares for my feelings ,and she is very helpful and always ready to listen to my problems. When I am sad , she will be the first person person to be by my side. What she will do is just to hear me cry without saying anything . And then she will take me to eat delicious food. She knows me very well even if I say something that others can't understand. So I think the two best friends of mine are not the same .
Nowadays, it seems that there are many ways to express friendship. Our lives are better and better. People now have more time to concentrate more on their lives. Money,which is considered by many people to be the most importance thing, makes it difficult to find true friendship. Is friendship expressed only by greeting each other on meeting? Is friendship expressed only by drinking and eating together? Is friendship expressed only lending money to each other? No!A friend Should be a person you believe in and understand. A friend should be a person who share their happiness and bitterness with you. A friend should be a person who can give you confidence and encouragement.
Though the definitions of friendship may vary,and everything may change.I believe one thing will never be changed,that is a friend in need is a friend indeed!
