Fool's gold anyway. Pyrite is one of my favorites. I had completely forgotten until this post, but when I was in maybe 4th grade(?) we had "Student of the Week". Did your school have that? When it was our week, we'd bring in a table display worth of stuff about us on Monday and present it to the class on Friday. Basically, an intense Show & Tell. I brought in my rock collection, and a boy in my class stole my pyrite because he thought it was gold. Really, that's what he said when his mother made him bring it back and apologize. I feel like there's some important life lesson or metaphor in there somewhere, but... I'm not connecting the dots right now.
