The other day, I was invited my friend Sam’s home for dinner. I felt a bit surprising when

I saw Bill there. It was two month since we two had quarreled, so I was embarrassed and

didn’t know how to do. I sat down on the sofa but began to watch TV. Later Sam came to

ask I to make up with Bill. Until then I realize that Sam had arranged the meeting on purpose.

I went up to Bill and greeted him warmly, smiled at him. He looked very happily and talked
