Dizni DeBerry, a Hillside High School senior in Durham, vividly remembers the week before schools closed. In mid-March, DeBerry, 18, and other students in Hillside’s vaunted drama department, after weeks of rehearsals, were preparing to perform Matilda: The Musical, a play based on the hit movie and beloved children’s book.  But students had heard rumors that Durham Public Schools could possibly close in response to the COVID-19 crisis.
