We push the bikes through fields of stinking black muck, the sun beating hot on our bare heads. My hair, shaved a week ago under bad light in a roadside toilet, is a snatch of silk on fire. Ahead of me the mechanic shows frustration, stomping dirt. When he turns to squint at me, his face is pinched with aggression. My throat scratches with thirst. I need to piss, but I’m afraid of appearing old and weak. Colette hated the humiliations that age brought, and remembering her determined efforts to appear youthful, I push with my legs, lower my face parallel to the plastic bike seat.
