Harvard Subway - Boston

Arrived in Boston in the early evening and got the Subway to Alewife where our hotel was. Today's picture had to be of the subway as everytime we got on the subway something kept making me laugh. First it was the man/woman, we weren't sure what it was and this random womans reaction when she sees it. Then later on another subway a woman gets on and sits opposite us and takes a picture of herself pouting with the phone facing us so we see the picture.
All I can say is people on the tube in Boston are crazy.
Boston is a pretty awesome city though!
