Every penny is different
You and I are all different. Even Andrew and I are different. Nobody is exactly alike. Nothing is exactly the same, if you look at it closely. I have a pile of 10 or so pennies, and I just go through them, saying "look at how different each penny is." Sometimes, we forget our own individuality. We let ourselves believe that we're just like everyone else, that we should strive for unification. We are all different people, though, and that's good.
