It's only lately that I have been game to sketch people in the train. So far so good. I choose those occupied with their own activities or a little further away. Sure helps to pass the time.
This was on a Friday evening after work, some people were obviously *very* tired.
On another occasion, a cute 6 year old boy sitting next to me took an interest in my sketching so I invited him to share my page. What a pleasant way to fill the half hour trip. Thank you Aiden!
