Michelle, I wonder if she would have taken the seat if you had offered it to her (of course there’s no way to know.)
I’ve long held the belief that humans are more attracted to the edges of the pendulum swing. As we try to find and accept balance in our lives, we tend to overreact in our efforts. Maybe feminism is really important to her and she’s trying not to accept everyday sexism that happens around her. Or maybe she was just tired of having people comment on her pregnancy and offer unwanted help and advice and your husband got more than his fair share of the backlash. I’m impressed that your husband had his wits about him to respond in a well-reasoned and polite way.
Thank you for sharing, it’s an interesting anecdote and food for thought.
