Pen, Paint, and Pretzels, the umbrella organization for student-run performing arts groups at Tufts University, presents the first of two performances of “Wink,” its spring semester workshop production, in the Sophia Gordon Hall Multipurpose Room. Written by Jen Silverman, “Wink” follows unhappy housewife Sofie and her breadwinning husband, Gregor, who both seek weekly counseling from an unorthodox therapist, Doctor Frans. Their current topic of disagreement: the cat, Wink. When Wink goes missing, violent desires, domestic anarchy and feline vengeance emerge, threatening the neatly ordered reality Sophie, Gregor and Doctor Frans have constructed. Directed by Katharine (Kay) Glimcher. Admission is free, but seating is limited and first-come, first-served; doors open at 6:45 p.m. A talkback will follow this performance. The second performance will be at 5:30 p.m. on Sunday, February 16, at Sophia Gordon Hall.
