A couple decides: This isn’t working. He says he’ll leave, and then he doesn’t. He stays and stays and stays. Through seventy years of marriages, bar mitzvahs, baptisms, and funerals, he stays. People get drunk. People get sober. People plan vacations. People die. Somebody wins the lottery. A baby grows up. Everybody dances. GO. PLEASE. GO. asks what it means to love somebody for a lifetime, and what a lifetime even means.
