What a wonderful topic.
I have to take commuter train AND the subway to and from work every day. I love to look around and listen to the people, and it just makes my day when someone acknowledges me and strikes up a conversation. I also try to make conversation whenever I can (without being a pest, or whatever). :-)
This morning there was a woman sitting behind me with a little baby, and they were having so much fun, laughing, cooing, etc. Listening to that totally made my day.
