After a triumphant 4-night run, Mean Girls closed with special recognition for seniors taking their final theatrical bow at the Chelsea Morrison Theater. Director Elaine Lifter spoke affectionately of her graduating cast and crew and presented them with flowers. For Henry Stafford, a cast member in each of the eight productions mounted during his time at Millbrook, it was a bittersweet curtain call. “Being in theater at Millbrook has meant so much to me,” said Henry, “it has proved to me what I am capable of.”
