The Nineth Week---------Same As Last Week

We were supposed to have the 4th exam today, but Professor Nero pushed back the exam to next Friday, which is definitely a good news for us. And my session this week welcomed three students in total, same number as last week. While waiting for the students to stop by in the room at CL, I found out another job. Taking photos for visitors. Sometimes, we also had a conversation go on: "Is this a class? I am sorry." "No, there is no student at this moment, please feel free to come in."
