    I had an argument with my friend Ben yesterday because his favorite movie, which I thought was not interested. After the argument, he went off without say goodbye to me. I was angry on him. In the afternoon I started to feel sad because he is my best friend. After school, I asked him if he wanted to go with me as usually. He gave me a strange look and turned away. But, this time, he does say goodbye to me quietly. Later, while I was watching TV at home, the phone rang. This was Ben and he said he was sorry for that he did. He felt like childish. I said never mind. Now I feel much better since we are still good friend.
