Her face did a thing that, if I were writing fiction, I would probably cut because it would read as over-acted. But I watched it happen. Her face went from polite, to offended, to performatively wounded, to actively angry, over about two seconds. She said, loudly — loud enough that every single person in the vestibule and the first three rows of car three turned to look — "Oh my GOD. Did you just refuse to give up your seat to a pregnant woman?" I said, calmly, "I did not refuse to give up my seat. I offered to get the conductor." She said, "You are SITTING on your SUITCASE. And I am PREGNANT. And you are telling me

to go find the conductor?" I said, "Yes." I said it the way you say things when you have realized, in real time, that you are about to be the subject of a story this person tells at dinner parties for the next year, and you have decided to accept that fate. She stood over me. She said, "You are disgusting." She pulled out her phone. She started filming me. And I did something that, later, I was very glad I had done. I looked directly into her phone camera. And I said, calmly, "I am happy to be recorded. I am also noting, for the record, that you told me you were pregnant in front of twelve witnesses who can confirm you do not appear visibly pregnant."
