This exchange happened today. While the kids were getting ready to go, I sat at my desk to get something. A student approached:
Student: Ms. M, do you have change for a $10?
Me: Actually, I think I do. (I got my wallet out and got out a 5 and five singles. I went to hand it to the student and saw that she was squatting down in front of my desk. I figured she had dropped her $10.)
Me: Here you go. (The student stands and we exchange money.)
Student: Thanks, Ms. M (and skips away).
Me: Uh, why is your $10 bill so damp?
Student: Oh, because it was in my shoe. Bye!
Ewwwwww! The money's still sitting on my desk "drying out."
