Enthusiasm in the high school classroom

I can’t tell you how many times students enter my room and say something like “I’m SO tired,” or “Man, I’m exhausted,” or “Mrs. Yung, I’m gonna sleep in class today because I CANNOT keep my eyes open.” This happens not just during my 8 a.m. first hour class, but all day long. I bet I hear someone tell me they’re SO TIRED about nine or ten times a day.
