Man on bus having difficulty with his cellphone stylus
This older man is using his stylus to write Chinese characters for a text message. He keeps having to take his glasses on and off to write it. He writes a few strokes, then presses a button, then puts his glasses back on, and then repeats the entire process. The bus is also very bumpy so he is trying to stablize the mobile with his hands.
Across the aisle, a girl is cutting her nails (picture below).
