I dated one in my life, who somehow got the entirely wrong impression that I was wealthy (I'm absolutely not. I'm barely lower middle-class, and have been all my life). She was nightmarish, unpleasant, and consistently the most self-centered person I've ever had the displeasure to date. I wish I could say the sex was worth all that, but it absolutely wasn't. All she had going for her was that she was pretty in a classical model-pretty sense, but that gets really boring really fast when you find out that behind that pretty face is a vacant brain and a garbage personality, and all the intimate skills of a hyperactive lemur.
That was super-early in my dating life when I was young and easily impressed by the wrapper and didn't look beyond it as much as I should have before saying "yes". I never made that mistake again.
