Although the heat had not yet broken she began that week to sleep inside, between white sheets, hoping dimly that the white sheets would effect some charm, that she would wake in the morning and find them stained with blood. She did this in the same spirit that she had, a month before, thrown a full box of Tampax into the garbage: to be without Tampax was to insure bleeding, to sleep naked between white sheets was to guarantee staining. To give the charm every opportunity she changed the immaculate sheets every morning. She wore white crêpe pajamas and no underwear to a party.
