You know what happens when you get a rock in your shoe that you can't get rid of? It sits there for a while. Eventually, you try to move it to the edge of your shoe. It still sits there, though, building up pressure. Then you get accustomed, for the meantime, and you try your hardest to push it further away, but it only goes so far. It always wants to creep back under your foot, into your arches. It really wants to get the best of you, and it doesn't even know it. Then you wise up. You undo the laces on that shoe and immediately feel the relief. You pull off the shoe and see the rock. It's sharp, with an annoying glimmer. It feels heavy, but it's really not. It sucks. It's stupid. It's a goddamned rock, and you don't want it anymore. Get it the hell out of here. So, you toss it onto the sidewalk. You toss it and walk away, never seeing it again. Then, a few kids find your rock, and start pelting each other with that and other rocks. What comes around, goes around. But never to me again. No more rocks in my shoes.
