One of my greatest high school regrets is that I never took an auto shop class. I would have had a chance to learn some practical skills like changing oil and changing a tire. At the time, I doubt it fit into my schedule, but entering a class of mostly boys scared me as well. It's not that I was afraid of boys—I considered myself a feminist despite not fully understanding what that meant—but it would still have been intimidating to walk into a classroom full of dudes.
When does this happen, this point where men are encouraged in the fields of science, technology, engineering and math and women are left out? My mother teaches kindergarten; in her class, all the kids seem equally excited by counting and banana slugs. But somehow, by the time women reach the higher echelons of education, there is sorting out, if you will, in which mostly men go in one direction and women in another.
