This winter vacation, I made an appointment with my teacher and went back to listen to a physics class.

At the door of the classroom, I saw his familiar face and more than 60 unfamiliar faces in the classroom. I suddenly got scared. Because the classroom is the same as the classroom I have stayed in, the school uniform, tables and chairs, and internal facilities are the same as when I graduated, but the people have changed.

No one sitting in the back seat of my car has been patting me on the back and posting me small notes. As soon as I turned around, she pretended to have a big face as if nothing had happened, although I always said that you had a big chest and no brain. No hero always pokes me suddenly in class and tells cold jokes. Although your jokes are really not funny. I never know what a punch line is. None of the girls were kicked off the bench for a month. I still like a child who likes someone but can't express it. I always do childish things, such as kicking the bench and touching my hair. No wonder you don't accept me.

The teacher pulled me to the podium and proudly said, this is your senior and my class representative for three years. Graduation is the first in my class, which is my pride. My eyes suddenly turned red, and the teacher still regarded me as his child, the representative of his class and his favorite student.

I was silent for a while and didn't know what to say. I held back: I wish my schoolmates a bright future and success in their studies. I don't know what to say about the rest.

In that class, it was a curve movement. And I remember the curve movement three years ago. Because the teacher found me playing with my mobile phone in that class, he didn't say anything. He just came over and quietly touched my low head, and then whispered, here comes the point.

Yes, this is the key to remember for a lifetime.
