I have a friend named Alex. He is my best friend. One day he broke his arm. He couldn't do to school and sat at home alone. After school I came to him. He was sad. He was very glad to see me. It was boring to sit at home. He decided to play computer games. Then we watch TV. I told him different funny stories. He was smiling all the time and almost forgot about his hand. Then we did my homework together. When it was 6 I had to go home. At home I talked with my friend on the Internet. . I went to him every day. He is my best friend and I will never betray him
