"I mean, I can do that all day long. I can tell you the Vulcan's are not actually devoid of emotion. That they work hard to suppress their emotions. And of course, there actually are no real Vulcan's, though I know the ins and outs of them as fictional characters."

Next Quote

Writing fiction lets you be a little more emotional and unguarded, a little freer. Writing fictional characters is also really different from writing about real people. In nonfiction, you can only say so much about the people you interact with. After all, they're actual people, their version of their story trumps yours. In a novel, you can build a character, using certain parts or impressions of someone you know, and guessing or inventing others, without having to worry that your guesses or memories or inventions are wrong.
