So much of what determines our happiness, I believe, is who we choose as our intimates.

One thing the passage of time has shown me is that you never know how you'll behave in a situation until you're in that situation yourself.

I don't know if make a conscious effort to vary the characters and subjects that I write about, but I do find myself keeping track of ideas that come along, as probably most writers do, and whatever seems most interesting to me when I flip through my notes before I begin a new story is usually what I will try to write about next.

Jealousy is a potent emotion, of course, and Facebook, texting, email, fan Web pages... In theory, being someone like George Clooney's or Halle Berry's paramour - woo hoo - how great would that be? But wait a minute... er, no, probably kind of a nightmare.

So much of what determines our happiness, I believe, is who we choose as our intimates.

Tangentially, Americans, despite many of us being prone to sometimes-eyebrow-raising disclosures about our private lives on social media, still retain what I think of as reactionary views about sexuality and intimacy.

I think that under ordinary circumstances (i.e., neither person is famous), it's already hard enough to make a long-term romantic relationship work, but add fame to the calculus.
