I used to believe everything my brother told me, because he was older and I figured he knew more about the world. But as it turns out, being a grown-up doesn’t mean you’re fearless. It just means you fear different things.

I adore the way he looks at me sometimes, as if love is a quantity he cannot measure scientifically, because it multiplies too quickly.

The brain of a person in love will show activity in the amygdala, which is associated with gut feelings, and in the nucleus accumbens, an area associated with rewarding stimuli that tends to be active in drug abusers. Or, to recap: the brain of a person in love doesn't look like the brain of someone overcome by deep emotion. It looks like the brain of a person who's been snorting coke.

I know that there will be other women, but they couldn't compare. Maybe I'll change, maybe love will change, but I think we were a once-in-a-lifetime. You could never leave me; that's why I am not more upset. You can't possibly break these feelings. They stretch, and they last.

Because hate's just the flip side of love. Like heads and tails on a dime. If you don't know what it feels like to love someone, how would you know what hate is? One can't exist without the other.

Even though I don't write about things that come from my life because I'm lucky, and I live in a great place with great kids and, you know, a great husband, I think you can find threads of me in the characters, so that's really what being a writer is, probably.
