I was on the subway this morning and it was a packed car. There was a medical emergency on our line, so we were stopped for a good 20 min. After about 10 min a woman offered me a seat saying "we've all been there, you should sit". I was getting a little overheated, so I took a seat. The guy next to her just looked at us both really confused and then kept glancing at me with a quizzical look for the rest of the ride.
