Where do you sit in a class?

Last week, my friend, Sun, and I met together, and decided to go for a short local trip, as well as did a little bit catch up. When we met, I told him how I has been busying from my new work, family stuffs, and my activities. Every Friday evening after work, I would take Mandarin class. Then, Sun said "Vincent, you must be the one sitting at the front row of the class." It was so truth; my face turned red. "What do you mean I must be the one sitting at the front row of the class?" I said. Then, he told me I alway look very serious in the class.

There are many reasons I choose to pick front row. Whatever, I think " You must be the one sitting at the front row of the class" will keep me laugh for a while.
