I'm also way too positive for my own good. Where others see a glass that's half-empty I see two fish that can feed 5,000 people (I'm not religious in any way).
Oh yeah, I have this weird obsession with languages. I'm just very interested in the etymology of all kinds of words. Having gotten to know some real linguists not too long ago I realized that I'm not nearly as knowledgeable about that topic as I'd like to be, unfortunately.
