You buy things and you keep them clean. You take care of them. Keep them in a special pocket. Away from keys and coins. Away from other things that should be kept clean and taken care of as well. Then they get scratched. And scratched again. And again. And again. And again. Soon, you don't care about them anymore. You don't keep them in a special pocket. You throw them in the bag with everything else. They've surpassed their form and become nothing but function. People are like that. You meet them and keep them clean. In a special pocket. And then you start to scratch them. Not on purpose. Sometimes you just drop them by accident or forget which pocket they're in. But after the first scratch, it's all downhill from there. You see past their form. They become function. They are a purpose. Only their essence remains.
