I think poetry always lives its life, and people come to it and people go away from it, 'people' in the sense of larger numbers of people. It's as though you begin to think that poetry is a resource, and that at certain times people seem to need it or want it or can find sustenance in it, and at other times they can't.
One becomes a grandfather and one sees the world a little differently. Certainly the world becomes a more vulnerable place when one has a grandchild, or now I have two. And I think that possibly there's some tenderness that came out of just time and age and being a parent and grandparent.
