Here are the usual train sketches - above on the way there and below on the way home. The man above's companion took photos on her phone the whole time, making really loud "shutter" noises. Every time he dropped off to sleep she did it again and woke him up. He never said anything though!
I was just thinking as I was drawing this man's hair how awkward it was to draw, when I happened to look at the piece of paper he was reading. It said "Firstly please accept my apologies for my atrocious hair." (At least that's what I thought it said until he moved his thumb revealing the word "handwriting." But I like my version better.)
Another common exchange in my life:-
SOMEONE: So, what are you doing at university?
ME: An MA in Children's Book Illustration.
SOMEONE: Oh! So you're arty then, are you?
