Me, in one sentence? OK, here goes...
I am an enthusiastic skeptic with a talent for verbosity, two qualities which lend themselves well to one another; as a skeptic it helps to be verbose because it allows me to convey a point thoroughly, while as a guy who likes to talk it's good to be a skeptic, because it puts me in the auspicious position of seldom being left wanting for things to talk about -- take this single sentence for instance: If I didn't have my talent for grammar, syntax, punctuation and all that other garbage, then this absurdly long descriptor -- itself steeped in self-inflating self-reference -- would have ended half a page ago, while if I didn't have my skepticism, then I'd likely have found some other interest on which to cut my linguistic teeth (an interest that would see me surrounded by fewer people interested in education in general and, in turn, less interested in appearing well-educated); ultimately, being a verbose skeptic serves me well, and particularly in situations where people ask me to describe myself in one damn sentence.
