Reading and Subway Conversations

I recently started to record conversations when I'm sketching people in the subway when my  view is blocked or I'm not in the mood for sketching for whatever reason (it happens). It's a fun way to get an even better picture of what was going on at the time and keep "taking your pen for a walk". 

Last night in the subway I was sketching this guy intensely reading a book and when he moved out of my view I started to record the conversation of people nearby. I like the result.
