Oh, the perils!
I think well-rounded people keep polishing their edges because they secretly hope that one day they can become so round they’ll just start rolling through life. I mean, it seems pretty great, doesn’t it? If you’re that well-rounded, you just need a tiny bit of momentum and not too much friction and you’re well on your way to wherever it is you’re going. The downside, of course, is that once set in motion, you may find it difficult to stop. Life as a perfect sphere also means it can be harder to choose the direction you hope to go, and unexpected breezes may send you careening in unexpected directions at any given moment.
Some well-rounded people go a step further, and attempt to make the stuff they are made of malleable. This has its advantages, you see, as the increased elasticity allows these well-rounded people to bounce over things that are slightly uncomfortable on the ground. Also, it means that when they reach doorways that aren’t quite suited to their shape, they force their way through anyway. Sometimes the people on the other end notice they aren’t of the same shape as most other people who have come through that door, but often they don’t care anyway. Hey, they figure, if you fit, you fit.
Other well-rounded people polish their surfaces to a gleaming hard finish. They figure with their momentum and firm exterior, it doesn’t matter what doorways they approach. They can just steamroll their way through, breaking down walls they want to get through and knocking whatever they want out of the way. It’s a rough approach, but people are often so blinded by their shiny surfaces that they just let them pass right on by.
I think some of the spheres forget how potential energy works too, so they’ll roll confidently up the hill only to forget they can roll back down just as quickly. Oops.
In contrast to those well-rounded spheres, most of us are born triangles. It’s really hard to get moving this way. You painstakingly flip over to one side, and then it takes a whole lot of effort to flip over to another side and make your next move forward. I guess one of the fun parts, though, is that occasionally your pointy edge pokes the tearable surface of one of those well-rounded people and they might deflate a little or get a little chunk taken out of them. Well, maybe it’s not that fun, but at least you both are temporarily stopped in your tracks and can enjoy a good laugh about it while they work to get their well-roundedness back and you think of how far they’ll have gotten once restored while you’ll still be stuck in this particular place for a good long while, since you’re a triangle.
