What a small world it is!

Today I ran into a student of mine again on my way home- this was the second time ever by the way. He used to take my TOEIC courses a long while ago, so it's history. By the time I saw him today, he was about to go jogging at the elementary school track near by. Since it had been a long time since we last met, I felt a bit excited seeing him again trying to chat more with him. What surprised me was that he said he had begun teaching at a university in Hsinchu, and then wait a second ... that is EXACTLY the same school that I will be teaching at this September. What a coincidence! What a small world! I told him that our relationship had changed from teacher-student to teacher- teacher. Wasn't that interesting?
