Ruth brought Lian home from a long medical appointment. Ruth: “Can I help? Can I set the table?” Me: “That’s Ezra’s job.” Ruth: “Is there anything else I can do?” A few minutes pass. Ruth: “Do you want me to empty the dishwasher? I guess that’s Ezra’s job isn’t it.” Ezra: “Now that I’m here, we really don’t need you anymore.”
