Paul took letter writing seriously; he'd set aside time for it, tried to document our day-to-day lives in a journalistic way, and usually wrote three to six pages a week in a beautiful flowing hand with a special fountain pen; often he included little sketches of places we'd visited, or photos, or made mini-collages out of ticket stubs or newsprint. My letters were usually one or two pages, typed, and full of spelling mistakes, bad grammar, and exclamation points; I tended to focus on what I was cooking at the time, or the human dramas boiling around us. Written on thin pale-blue or white airmail paper, those hundreds of letters have survived the years in very good shape.
