Serious Reading and Chinese Numbers

On the subway the other day I started sketching this man who was seriously reading the newspaper right in front of me. As I was drawing, a Chinese girl sitting beside me, complemented me on the drawing and we started talking about what we do, and languages we speak. I told her that I used to know how to write all the numbers from 1 to 10 in Chinese, but I forgot most of it. I went on to draw numbers 1 to 5 and wasn't too sure after that. She showed me the rest of the number sequence and then she showed me how she could draw an old man based on various Chinese characters. How cool is that! You never know what you can learn from people around you in the subway :)
