I like to think I'm fairly neutral on judging people by their appearance. I've known enough fine people whose clothing and grooming leave a lot to be desired, and enough pretty exteriors hiding vacant brains.

What people say or do when I first know them is the influence, but it isn't always right. As an example: a woman I met seemed (and still does, after fifteen years) a complete airhead, went to university and seems to have forgotten everything she learned, hasn't a clue about anything I might have an interest in talking about. But after a few years I noticed she's managed to raise two very fine sons who love her to bits (and tease her unmercifully). I tried to pay closer attention to her after that realization, and I suspect the airhead presentation is a sort of fabricated 'cover', that she discovered eased a lot of pressure over the years when she has had too much work to do to bother with a 'winning personality'.
