This year was my first year of student teaching. During a lecture this past spring, my students were quietly laughing, but when I'd turn around and ask them what they were laughing about, they'd say "nothing." Finally, I turned to one of my students that I can usually trust, and asked him what was up. He said, "Um, Ms Jones....your belt is undone..." Who knows why they thought that was the funniest thing in the world, but I'll tell you that I always check my belt buckle now!!
