Performers Meggie Mapes and Mike Selck rehearse “Under the Mantle,” a play they co-wrote, that describes the conflict between relationships and daily life. “What we are talking about are world view shifts,” Selck said. “Thinking about the same phenomena from two different view points.” “Under the Mantle” and “Astigmatheism,” a play written by Angela Glunz and co-directed by Glunz and Stephenie DeArcangelis, will play back-to-back Thursday through Saturday at the Marion Kleinau Theatre in the Communications Building.
