Riding on the 'T' (or train) in Boston, I got a seat for a couple of stops so I pulled out my sketchbook and drew the guy across from me and the woman in the cool glasses next to me (we were facing the window and it was dark outside so it acted like a mirror).The guy was with a woman who could have been either his young mom, or his older girlfriend. I don't know if the woman next to me knew I was drawing her as my stop came up fast and I had to jump off the train.
