Loved talking to Noah, one of my favorite commentators, about my book!!
I interviewed @corinnelow.com about her book Having It All, and how sexism and men's unwillingness to do domestic chores and childcare puts a lot of constraints on what women can in fact have. Important to recognize that and make decisions accordingly! www.everythingishorrible.net/p/how-women-...
