On Friday night, while drawing the top one, an elderly Asian lady leaned across the aisle to talk to me. I got into a lengthy conversation with her about my drawing, the festival I was on my way to and her grandchildren, who live in Newcastle. Afterwards, I discovered a lovely email on my phone from someone else on the train who had also watched me sketch the sunset and had been listening in on our conversation.
As you can read on my notes on this drawing, which I did next, the email was very kind about both my drawing and my people-skills. I looked all round for give-away signs of who it could be, but couldn't tell.
