"Can I grab a picture with you? Great, thanks. Now, could you look contented, yet melancholy? Like the weight of the world is on your shoulders? And here is the last place you want to be, but you're here anyway, at the last place you want to be? I'd really like to see it in your eyes in this. Maybe you could even throw in a little despair, like you're thinking about the world issues. Yeah, contented, melancholic despair.
Or you could just smile. How boring.
I may over-think things.
