Yes wolf- al tarbeh meaning only whatever is necessary.
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?
