My curls tickle my face. My fingers feverishly sort though papers. I make last-minute decisions for the day. A former student, who stops by every day, chats by my side. It’s 7:30 a.m., and I’m depending on Folgers to usher me into a coherent state when I hear this student say, “Mrs. Yahn, ever since your class last year, I just can’t stop talking. I used to say nothing in class, but now I talk all the time. You taught me that.”
