Why buy the cow if you can get the milk for free? This rather antique view was held by my grandparents’ generation, which apparently equated milk with sex and women with cows. You can see what I mean by antique. This warning for young women implied that all men wanted from marriage was sex, and this was a commodity that must be withheld until he was trapped with a marriage certificate. But people have been more free with love since the sixties, and they still get married and have children. Apparently there are more reasons to get married than just sex. Dare I say love?
