Because I'm a teacher...

I get to experience honest moments like these:

D: Mrs. M., is Valentine's Day on the 14th of February?
Mrs. M.: You bet. I think it's a Monday this year.
D: Do we have school that day?
M: *Snickers* and tries hard to hide the amusement. Doesn't work.

When asked why she was doodling instead of doing her math, J pauses for a few moments and says, "Just trying to pass the time."
