By the time we reached Santa Fe, the story had already begun to feel like something borrowed—too luminous, too neatly threaded through decades to belong to us alone. In the hotel room, the air‑conditioner hummed and the desert light slanted in, turning the curtains the color of apricots. My mother sat in the armchair by the window, the wide‑brimmed hat the oncologist had insisted on tipped back from her forehead.
