There could be something freeing about being truly ugly. Not just bad skin and an overbite ugly, but really deformed. If you are the former, you will spend huge amounts of time-energy-money trying to fix your skin, find the best haircut or neckline to downplay your overbite, etc. But if you are the latter, if there is really no hope you could ever be attractive, you will give up on it and funnel all your energy into being brilliant and unconventional and kind.
It’s astounding, really, to hear what someone admires in you. I don’t know why we don’t go around thoughtfully complimenting one another all the time.
