Writers obviously have to bear witness to the harsh face of the age.

I've also long since realized that the way to really engage children is to give out prizes it's amazing how it concentrates their minds.

My wife Elizabeth and I started The Really Terrible Orchestra for people like us who are pretty hopeless musicians who would like to play in an orchestra. It has been a great success. We give performances we've become the most famous bad orchestra in the world.

It's through the small things that we develop our moral imagination, so that we can understand the sufferings of others.

But you cannot expect every writer to dwell on human suffering. I think my books do deal with grave issues. People who say they are too positive probably haven't read them.
