This is an episode about gender roles and how the balance of both sides (in a relationship) are important. It was not about who's home or who's working, it was about balance both sides. We see how the wife needed to behave more "care giver" just as the husband needed to be in control more often. It's not about him "being the man" or her cooking. It's about both of them being both sides at the same time, all the time. She works, but she also cares and takes care of children and her husband. Just as, he may be busy with the kids and all house cleaning, but he knows he has a wife, in need of some more action from him. In general, we understand that if we just play a role, both sides lose each other. We understand that a relationship needs a balance between both sides, that goes deeper than gender roles. It's about share a bit of both with the partner.
