There's a funny story. As a course requirement, a group of students leads a discussion of class every week. Our turn is on 25th. Today my group consisting of 3 people was supposed to have a first meeting before a class. However, there were so many things to do and couldn't prepare for a meeting. So I sent e-mail that I would like to postpone the first meeting to next week. One student gave me a reply that she agrees with it because she also couldn't prepare for it. We were waiting for a reply from the last student of our group. Unfortunately we didn't know his phone number. Because we couldn't get an e-mail from him, we decided to go to a meeting place anyway. We waited and waited but he didn't come. Eventually he didn't show up in a class, either! How can I contact with him!?
