Gathered in the parks of Oaxaca during the early 2000s, groups of high school friends, including our dear Roberto, would herald in the end of another school year and the start of a summer of easy living with refreshing nieves in hand. A cup of icy, colorful nieve marked the beginning of carefree afternoons and liberation from homework. Lined up in their wooden containers, the diverse and bright array of fruit nieves resembled the exuberance of the summer unfolding around us: the rich green of the trees, the gentle yellow of the afternoon sun and petricor – a beautiful Spanish word describing the subtle and comforting smell of moist earth after rain.
