This never happened to me before. A woman who was exiting the train at MacArthur went out of her way to grab me and said, "You look sick, here, take my seat, I am leaving."
It is true that I'm feeling a bit of a cold coming but I didn't think it was visible. Do I look that awful today? Maybe she just wanted to give the seat to a female and had to come up with a reason why?
Regardless, I appreciated it. It was nice to sit down. I haven't had a seat en-route to SF for a few weeks. It's been increasingly crowded these days.
