Pen, Paint, and Pretzels, the umbrella organization for student-run performing arts groups at Tufts University, presents the first of two performances of “The Wolves,” its fall workshop production. “The Wolves,” a one-act play by Sarah DeLappe, centers on the experiences of high school girls through their weekly Saturday morning pre-game soccer warmups. Appropriately, the production will be performed in the Carzo Cage, the indoor turf field in between Cousens Gym and the Steve Tisch Sports and Fitness Center. Tate Olitt is the director, with Lindsay Diab the stage manager. Free admission; no tickets required. The second performance will be at 6:30 p.m. on Sunday, December 3, in the same venue.
