I've been a hard core nerd my whole life. Even before being a nerd was "cool." Don't ask me about RPGs, CosPlay or SciFi shows/movies -- not that kind of nerd. I'm a STEM Nerd. I am also an actor and a teacher, trying to develop my artistic side.
I say that English is not my first language, even though I was born & raised in the US with an English speaking household. My first language was the "language" of science & math. I understand these concepts. Words came later.
Today, I still struggle with the subtleties of language & social interactions.
