Elizabeth knew three tips, or her "keeps" as she liked to call them, on how to be a good wife: 1. Keep his belly full 2. Keep the home clean 3. Keep your mouth shut when he comes home with blood on his jacket. A marriage purely of convenience back in 1920, the Hellers made a comfortable life for themselves in the city, with Elizabeth staying home to care for the house and Mordecai 'bringing home the bacon' as they say. A pretty nice little setup, don't you think?
