"What are you going out at this time for, Ms?"

It's 7 pm now. It's raining continually. Jianzhi saw you by chance on the street. He has just been off work from the university. You are walking on the street in a formal outfit. The road is so slippery that everyone can fall. Jianzhi is a university professor and you are a primary school English teacher. You two met each other by chance in Tianjin University in an event held by the school. If you and he hadn't talked to each other, perhaps you wouldn't have known both used to be formal students in Qinghua University. He is 3 years older than you but you had never seen him when you were a university student. You were in English Linguistic Faculty and he was in Literature Pedagogy one. Sometimes, you and he get to meet to discuss about work or confide.
