So the coffee did what no amount of willpower could do, huh, it finally killed the tracker. Gotta respect that level of commitment from a beverage. But honestly you're not wrong about the ugly grid being the point, I kept a wall calendar for a year and the months where I fell off looked like a crime scene, and that mess actually told me something. The blank start-over version tells you nothing except that you're good at pretending. The data is the whole reason the thing works, even the bad months, maybe especially the bad months. So yeah, fix the layout, laminate the thing, and put your mug somewhere else. One spilled coffee is a story you tell later, not a reason to burn the whole record.

Man, I read somewhere that a dull blade is way more dangerous than a sharp one because you push harder and slip. I keep a spare blade for my mandoline in the bottom of my knife roll now after getting burned once. Sounds like you handled it about as good as anyone could mid-rush though.
