Host Meg Wolitzer presents three stories that cross generations. In Justin Torres’s “Trash Kites,” performed by Colman Domingo, teens find beauty in scarcity. A daughter’s aging parent links her past and present in “The World with My Mother Still in It” by Kathryn Chetkovich, performed by Phillipa Soo. And a tutor tries to create a bond with her privileged student in “Ancient Rome” by Kyle McCarthy, performed by Tavi Gevinson.
