Leo shared the memories during an unscripted visit with the children of Vatican employees who are attending the Holy See’s summer camp. They were joined by other children, including Ukrainian young people, who are attending summer programs run by Italy’s Caritas charity. One of the young campers, Giulia, asked Leo if he used to go to Mass as a child. Young Robert used to pretend to celebrate Mass using their mother’s ironing board as an altar and Necco candies — a once-popular sweet — as Communion wafers. History’s first American pope spoke in Italian, but he switched to English to address a group of Ukrainian children, some of whom held up Ukrainian flags and snagged Leo autographs.
