"Women don't have to be but it is the feminist ideal to be encumbered by a husband and children. If she had a child (and didn't put it in a day care) she may not be a SC nominee today but a 'plain old housewife'. I can't tell you how many times career women have pulled me aside and asked me what I'm going to do about my education after I get married."
I am sure you told them you plan to USE your education, that is how you figured out if this "man" was smart enough for you..... (I am only half kidding)
Actually, I did a very un-womynist thing and picked a man smarter than me with a better degree :-)
