In the car, I secretly had a look at him through the rearview mirror (后视镜). He looked sad. “What’s the matter, honey?”“I’m nervous. I don’t know if I’ll be able to learn everything in the first grade. What if I can’t pay attention in class?”

My heart melted. I remembered being nervous on the first day of school and I thought I was the only student who felt that way. I was a nervous kid full of self-doubt. Seth behaved much better than I did.

We walked into his school together. He remembered where his new classroom was and recognized his teacher from the ice cream social party they had the day before. He sat down at his desk and chatted with a few of his classmates. He took a few photos of them (with a camera phone because I didn’t allow him to bring the real camera) and then he said in a very serious manner, “Mom, you can go home now. I’ll be OK.” And so he was.
