The Backstory:

Maker, Cat Rocketship, is at a craft show and just finished setting up. She's got her paper and pens out and is ready to draw. Pencil in hand, she's about to begin a warm up portrait of some Tumblr girl, and her friend turns to her and says, "Draw a cat."

So she draws the cat, and when she's done, friend takes the drawing away and starts writing on it. The page she returned inspired laughter all day.
