One day, I was going to attend an interview, what makes me amazing is that the interviewee is my classmates of middle school when he looked at a document carefully, it makes me depressed and my first reaction is to run away, I used to laugh at him when he took mincing steps and couldn't make a good presentation in the class. However, maybe he didn't recognize me since we had graduated and didn't contact each other for so long a time, I nearly got mad and thought it again and again, I decided to try at last and took it easy, meanwhile, I heard someone said "Hi, Tom, what a small world!"
