Min Green and Ed Slaterton are breaking up, so Min is writing Ed a letter and giving him a box. Inside the box is why they broke up. Two bottle caps, a movie ticket, a folded note, a box of matches, a protractor, books, a toy truck, a pair of ugly earrings, a comb from a motel room, and every other item collected over the course of a giddy, intimate, heartbreaking relationship. Item after item is illustrated and accounted for, and then the box, like a girlfriend, will be dumped.
