I'll try not to get into a long essay about this, because I totally could, and I drank coffee, which makes me chatty...
I'm not sure what "beauty" really is to me. I know that I find people beautiful without ever seeing them, so it can't be looks, and seeing them always makes it better. I know I find some people beautiful that others might see as having bad/ugly personalities, too. And I don't just mean the "bad boys and girls", I mean all people. ^^
I always try to bring out the beauty of a person, no matter what they do, how they talk, their background... These are all superficial things, what they want to portray, or they simply have never learned to portray anything better... but once you dig deep enough, you just see it. Real beauty.
