0 One day, I'll learn.

One day, I'll learn.  I'll learn to always finish the word I'm writing on the Smart Board BEFORE I stop to answer a question.  This is especially important when you're determining if a relation is a function.

Yeah, I might have only wrote the first two letters of the word function before stopping to answer a student question.  When the entire class starts laughing and you haven't told a joke, it's never a good sign.

That's a tough one to recover from.  One day, I'll learn.
