When I was a kid, half the houses on my block gave out rocks on Halloween instead of candy. Especially if your costume wasn’t up to neighborhood standards. By the time the last porch light was extinguished, we’d be making our way home in the dark, our masks half on and half off, dragging a heavy bag of rubble behind us. And we were happy to have those rocks. Thrilled, even. Sometimes, if you were lucky, some of the houses in the nicer neighborhoods would hand out full-size quartz! You can’t find those just lying around in the street. Charlie Brown can whine all he wants about his Halloween haul, but I’ve never heard of rocks giving anyone cavities or a tummy ache.
