I live in southern Appalachia, so I'm surrounded by people who work very hard for barely a living wage. It's particularly painful that people are working the farms their parents and grandparents worked but aren't living nearly as well.

But we've all ended up giving body and soul to Africa, one way or another. Even Adah, who's becoming an expert in tropical epidemiology and strange new viruses. Each of us got our heart buried in six feet of African dirt; we are all co-conspirators here. I mean, all of us, not just my family. So what do you do now? You get to find your own way to dig out a heart and shake it off and hold it up to the light again.

It's very important to distinguish between innocence and naivete. The innocent do not deserve to be the victims of violence. But only the naive refuse to think about the origins of violence and to pursue the possibility that the genesis of that hatred could be addressed.

The changes we dread most may contain our salvation.

Mexico admits you through an arched stone orifice into the tree-filled courtyard of its heart, where a dog pisses against a wall and a waiter hustles through a curtain of jasmine to bring a bowl of tortilla soup, steaming with cilantro and lime. Cats stalk lizards among the clay pots around the fountain, doves settle into the flowering vines and coo their prayers, thankful for the existence of lizards. The potted plants silently exhale, outgrowing their clay pots. Like Mexico's children they stand pinched and patient in last year's too-small shoes.

Plants do everything animals do, but slowly. They migrate, communicate, deceive, stalk their food and, with an ostentation of styles and perfumes to put the animal kingdom to shame, they make love. It's just that catching them in flagrante delicto might require time-lapse photography.

Sleeping alone seemed unnatural to me, and pitiful, something done in hospitals or when you're contagious.
