Sketches on the train, tube and train station in August II

I met a little boy on the train today and he was quick to spot me sketching, sometimes I wonder why children always spot me and are free to start talking straightaway. He saw the pens I used to sketch and instantly told his mum he wanted to get that pen. His mum was quick to tell him getting the Pen would not produce sketches like he saw, but constant practice. I encouraged him to draw everyday. Apparently he was on his way to the National Portrait Gallery, where his dad was to play his cello in the foyer.
