I get a good laugh at this scene. Is he being a patronizing sexist? Of course he is! Why should the woman not be let in on the secret? To suggest it is not proper for a woman to know this or that is in no way a bad thing. The desire to protect and preserve a woman’s innocence, or merely to acknowledge that some women should simply not have knowledge of certain information, is a good thing. Perhaps I am just way too old fashioned in certain regards. But no matter the amount of shaming, this will always be my way of thinking.
