well, my Co-workers often call me "an abundant source of Information nobody will ever need to know"
if I wanted to be more specific.. I do know quite a abit about Various Ancient Mythologies and Cultures..
In RL my expertise changes on the given situation. Normally I'm pretty fun to be around I love making people laugh, combine that with some acting ability and I'm the "Funny guy". But people also refer to me acting very "mom-like" despite the fact that I'm a 17 year old man, but that comes from the fact that I keep my friends out of trouble and I can cook, clean, sew etc. and have used these skills in various situations.
Music and history, I think. I study history at university and I consider myself fairly competent in the period from 700-1400. When it comes to music I play a number of different instruments and I study a lot of music theory. I also listen to everything from Ancient greek music to Avicii, and besides particularly obscure bands and artists there are not a whole lot of periods, movements and genres I'm not at least somewhat familiar with.
I know a little bit about everything, but music and history is my [censored].
This is such a temptation for my vanity, because I love being a "know-it-all". I will take up a trivia challenge in a lot of different areas. All kinds of popular culture, scientific, political and philosophy topics. I will tell you what I think about almost anything, but that doesn't mean you will agree or even care. I just like to understand systems of all kinds. But this gets me addicted to internet arguments.
I am the resident expert of uselessness. No skill or talent of much recognition. Don't got much to give out, either. I'm just a gargoyle whose eyes are hard and if given too much attention, especially in a mocking way, you can hear the faint grinding of teeth.
