Describe Brunos grandparents

Bruno's father's father ran a restaurant in the center of Berlin for most of his life. He was supportive of Father's promotion to Commandant. Bruno's father's mother is sixty-two with "long red hair and green eyes" (87). She is a retired singer and when Bruno's family lived in Berlin, she would put on plays with Gretl and Bruno during parties. She is furious to find out about Father's promotion to Commandant and storms out of the house during a Christmas party.
