“So, I suppose that all unnecessary conversation with one’s wife is also forbidden, since the Mishna specifically includes one’s wife?
So, no saying “good morning” to my wife? It’s not really necessary. No talking about books we’ve read? It’s not really necessary either. No pleasant chat over dinner unless we’re talking household matters? No talking while we’re taking a walk?”
YES thats exactly what it means. You talk to yur wife so that yur house can function normally and you raise the kids. Theres no heter for frivilus talk like good morning or talking about books or anything else thats not important.
