An ex and I were on a bus trip to a city about an hour away from where we lived while we taught English in Korea. The subject of there being a “subway” in said city came up randomly. She said she thought she had seen one the last time she was there. I had been there more times than she had and said there was no subway. She doubled down. No, she was quite sure she had seen one near the university. I doubled down, I’ve been there quite a few times. There’s no way they have a subway. It’s not even big enough for one! It got pretty heated. This went on for some time. Feelings were hurt.

She was talking about the sandwich restaurant, and I was talking about underground trains. We were both right.
