I'm drawn to people who find themselves on the outside of things. I'm moved by that in real life.
In writing about Harold and Maureen with their terrible unspoken secret, and all those people that Harold meets as he walks to save a friend's life, I was trying to celebrate the ordinary people.
I like writing people from a slightly sharp angle and then throwing more light on them. I think in life we see somebody and make judgments very quickly about who they are and what they are. Or we think people are boring because they appear ordinary.
