I don't know if Song Yan and I are friends, but in my heart he is as important as my family. I am used to waiting for the bus to go to school with him every day. I am used to handing him the bottle of water in his schoolbag when he is thirsty. I am used to standing by and silently cheering for him when he plays basketball. I am used to being the first to applaud him after the teacher praises him. I am used to helping him clean up more and more love letters in his desk. It would be great if I could keep doing this.
