If you're not home, does Mrs. Browl stand by the street outside your house, trying to flag down a male driver to open her jar? Division of labor is fine when it's convenient. Helplessness is not. Women living alone don't have to return a tightly sealed jar to the grocery store and get a refund. They just open the damn jar. It's a mystery how they do it, but I suspect it has something to do with not actually being as weak as they let on.
