“May I respectfully suggest that if the husband and wife disagree over a decision and the husband resorts to taking out his male trump card to take advance of a perceived male right to make the final decision, he will always choose his own way. It is because there is always selfishness tied to a trump card.”
Doctor: With this operation Mrs Smith, you will be able to walk much more comfortably, with less pain.
Mrs Smith: It is just too expensive, I will just have to manage as I am.
Mr Smith: It is expensive dear, but I am sure we could find a way. I insist that we go ahead.
How does this sort of situation fit in with “always selfishness” tied to a trump card?
