If you think about Don Quixote, Don Quixote is this guy who wants to live as if he was in a medieval chivalric romance, when actually he lives in sixteenth-century Spain, which is already going through secularization, industrialization, modernization. He goes out to kill a giant, and instead he collides with this huge windmill and injures himself and also damages the windmill. I think that's a metaphor for the collisions we all have over time, as our ideas of ourselves get out of synch with the historical moment.

It's really a trade-off: you're always having to decide whether you're going to say the more ambitious thing, and lose a little clarity - or are you going to say something really clearly, and sacrifice a little nuance? Get too obscure, and you sound like a pretentious asshole; go overboard with the clarity, and you sound like you're talking down to your audience, or like you yourself are a reductive simpleton.

In a lot of ways, being a writer is a lousy job - grueling, emotionally taxing, terrible hours, no health care - so if it wasn't about love, what would be the point?

I thought clarity of communication was the most important thing in writing, and if you really cared about getting your idea across, you would say it in the most straightforward way possible. Later, in college and grad school, I came to realize that language is a technology like any other, and that it's always evolving - clarity of expression is always evolving.

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.

I've been thinking a lot about why it was so important to me to do The Idiot as a novel, and not a memoir. One reason is the great love of novels that I keep droning on about. I've always loved reading novels. I've wanted to write novels since I was little. I started my first novel when I was seven.I don't have the same connection to memoir or nonfiction or essays. Writing nonfiction makes me feel a little bit as if I'm producing a product I don't consume - it's a really alienating feeling.

Part of flirting is that you tend to give each other a little extra slack to be obscure - to say things that are suggestive and nuanced, rather than clear and comprehensible, things you wouldn't put up with in an essay or something written by a stranger - and that can be so exciting.
