And the reason I am writing this on the back of a manila envelope now that they have left the train together is to tell you that when she turned to lift the large, delicate cello onto the overhead rack, I saw him looking up at her and what she was doing the way the eyes of saints are painted when they are looking up at God when he is doing something remarkable, something that identifies him as God.

But tonight, the lion of contentment has placed a warm heavy paw on my chest.

When you get a poem [in a public place], it happens to you so suddenly that you don't have time to deploy your anti-poetry deflector shields that were installed in high school.

Poems are not easy to start, and they're not easy to finish. There's a great pleasure in - I wouldn't say ease, but maybe kind of a fascinated ease that accompanies the actual writing of the poem. I find it very difficult to get started.

I think my work has to do with a sense that we are attempting, all the time, to create a logical, rational path through the day. To the left and right there are an amazing set of distractions that we usually can't afford to follow. But the poet is willing to stop anywhere.

I'm a line-maker. I think that's what makes poets different from prose-writers. That's the main way. We think, not just in sentences the way prose writers do but also in lines. So we're doing these two things at the same time.

The first line is the DNA of the poem; the rest of the poem is constructed out of that first line. A lot of it has to do with tone because tone is the key signature for the poem. The basis of trust for a reader used to be meter and end-rhyme.
