I write this letter to you when I feel well. I don't know how to say my thanks to you. I can't imagine what wuold happen that terible day withowt your help.my parents went to word. i stayed at home alone. suddenly, i felt very tired. I can't breath. I thought i was going to die. And you came. you called the doctor for me. And took care for me during that time. I think you are my real best friend. You tried to make me came calm by telling funny stories. althought, i was very tired but i felt very happy I knew that you and me are best friend! I am really a lucky man when having you!. You know, when my parents came home, I told what happened to me and what you did to help me. They said that you were really a kind friend! I am very pround when having a friend like you!
Now I am better. I please get my thanks
Your friend
