Can you imagine an all women professional conference? There's a big conference in a serious professional field and it's all women! You show up, you give talks, you listen, you take notes, you hardly notice that there are no men. Or maybe there are two or three, but they're easy to ignore, because in this very serious field, the opinions of men aren't very well respected.
Ok, such a conference doesn't exist. But men get to do this all the time. I'm currently working a temporary job that involves handing out credentials to various crew members of the memorial day concert at a desk in a hotel lobby downtown. Today, about 60 people, all of them men, asked me how to get to the Army Corps of Engineers meeting being held downstairs.
