Yesterday I was thinking about how I have been explicitly told to judge people by their shoes, teeth, and nails. Somehow I'd never examined that idea before, or doubted it, or questioned it. I don't think I like it, at least not as an absolute. Sure, you can glean little bits of information about someone by looking at their shoes or their teeth or their nails, but judging seems wrong.
Though come to think of it, maybe the explicit part has been the specification of shoes and teeth and nails. I'm not 100% sure that *judging* was made explicit.
I hate culture where shoes matter beyond the issue of how easy they are to walk in.
