The woman sitting behind me on the train kept saying into her phone, “he was obsessed with talking about my vagina. Is that weird?”
I was trying to listen to her conversation. But now her voice was lower. “Should I feel guilty about what I did?” she was saying. I really wanted to know what she did.
Anyway.
At that moment, I was going into the city to give a talk about college education to an audience of about 150 education experts.
