Knowing vs. Understanding

When you think you know someone, stop thinking. Nobody is who they seem to be.

All classes have that smart-ass kid, right?
Well, the one who sits next to me in health has an alcoholic mother who's never there for him and doesn't care much at all. I learned this when he told me that she's his anti-drug and showed me a picture. She's drunk in the picture.

I'm glad I understand him better now...Even if only slightly better.
