It's raining.

the kind of rain that comes down so heavy it sounds like the shower's running, even when you've turned it off. The kind of rain that makes you think of dams and flash floods, arks. The kind of rain that tells you to crawl back into bed, where the sheets haven't lost your body heat, to pretend that the clock is five minutes earlier than it really is.

Ask any kid who's made it past fourth grade and they can tell you: water never stops moving. Rain falls, and runs down a mountain into a river. The river finds it way to the ocean. It evaporates, like a soul, into the clouds. And then, like everything else, it starts all over again.

I didn't want to see her because it would make me feel better. I came because without her, it's hard to remember who I am...

In the end, though, I did not kill my sister. She did it all on her own.

Or at least this is what I tell myself.

Here's my question: What age are you when you're in Heaven? I mean, if it's Heaven, you should be at your beauty-queen best, and I doubt that all the people who die of old age are wandering around toothless and bald. It opens up a whole additional realm of questions, too. If you hang yourself, do you walk around all gross and blue, with your tongue spitting out of your mouth? If you are killed in a war, do you spend eternity minus the leg that got blown up by a mine?

I figure that maybe you get a choice. You fill out the application form that asks you if you want a star view or a cloud view, if you like chicken or fish or manna for dinner, what age you'd like to be seen as by everyone else. Like me, for example, I might pick seventeen, in the hopes I grow boobs by then, and even if I'm a pruny centegenarian by the time I die, in Heaven, I'd be young and pretty.

Once at a dinner party I heard my father say that even though he was old old old, in his heart he was twenty-one. So maybe there is a place in your life you ear out like a rut, or even better, like the soft spot on the couch. And no matter what else happens to you, you come back to that.

The problem, I suppose, is that everyone's different. What happens in Heaven when all these people are trying to find each other after so many years spent apart? Say that you die and start looking around for your husband, who died five years ago. what if you're picturing him at seventy, but he hit his groove at sixteen and is wandering around suave as can be?

Or what if you're Kate, and you die at sixteen, but in Heaven you choose to look thirty-five, an age you never got to be here on Earth. How would anyone ever be able to find you?

I used to wonder about the fake pictures that came in frames you buy at the store—ladies with smooth brown hair and show-me smiles, grapefruit-headed babies on their sibling's knees—people who in real life probably were strangers brought together by a talent scout to be a phony family.

Maybe it's not so different from real photos, after all.

Do you ever wonder how we all got here? On Earth, I mean. Forget the song and dance about Adam and Eve, which I know is a load of crap. My father likes the myth of the Pawnee Indians, who say that the star deities populated the world: Evening Star and Morning Star hooked up and gave birth to the first female. The first boy came from the Sun and the Moon. Humans rode in on the back of a tornado.

Mr. Hume, my science teacher, taught us about this primordial soup full of natural gases and muddy slop and carbon matter that somehow solidified into one-celled organisms called choanoflagellates... which sound a lot more like a sexually transmitted disease than the start of the evolutionary chain, in my opinion. But even once you get there, it's a huge leap from an amoeba to a monkey to a whole thinking person.

The really amazing thing about all this is no matter what you believe, it took some doing to get from a point where there was nothing, to a point where all the right neurons fire and pop so that we can make decisions.

More amazing is how even though that's become second nature, we all still manage to screw it up.
