K-K-Kathy?

Today, during Calculus, we were learning the derivative. Our teacher had written on the board that old equation: f(x+h)-f(x)/h. While she was explaining each bit (BTW, Jake, remember that time you taught this to me? That was awesome.), she made sure to use a different color for each new part.

As soon as she broke out the blue pen to break down the "-f(x)", I jumped back in my seat (it's Totally possible, problem?) and was hit with a wave of nostalgia.

Stage-like classroom.

Everyone at the board for some sort of mini-quiz.

David napping.

More colors of chalk than I knew existed.

Celli's Huge fancy notebook. Where'd you get that?

Everyone somehow getting the cheat codes for Sequences and Series.

Cockney bleedin' accents.

This was magnified because earlier in the day I saw someone with gray hair walking toward me a ways off with jeans and an old green T-shirt. Kathy? No, couldn't be.

But I like to think that, somewhere, somehow, whenever someone uses color-coded chalk to explain anything, Kathy is smiling.

And whenever someone has no fcuking clue what the fcuk a fcuking Proof by motherfcuking Induction is, she's smiling even wider.
