Recently, while I was in England, I saw a documentary on the BBC about the border between India and Pakistan at Wagah. When the border closes each evening around six o' clock, the soldiers on each side do these amazing high-stepping peacock march-offs (like a dance-off). The displays are almost identical on each side and thousands gather to watch them. Though they're patrolling along their separate borders, what comes across is how similar they are.

Some of my favorite poems are "confessional" poems written in the voices of aliens ("Southbound on the Freeway" by May Swenson" and "Report from the Surface" by Anthony McCann), sheep ("Snow Line" by John Berryman) or a yak ("The Only Yak in Batesville, Virginia" by Oni Buchanan).

Whether you're talking about political borders or aesthetic divisions (and clearly, the political ones have much more tragic consequences), it seems like once they are created, we want to patrol them, enforce them.

I think poetry involves heightened noticing or imagining as well as creating a certain made shape. On the other hand, that shape can be made just by pointing at something and saying, "That's a poem".

Writing directly from a feeling of anger or sadness is difficult, but if you distract part of your brain with word games, the ignored emotion often tiptoes in.

There isn't a grand plan at work in the progression of the books with respect to the line. I do want the books to be different from each other, certainly, but I'm more aware of that on the level of theme or structure. I can tell when I'm writing the last of a particular type of poem because the writing is too easy and I start to feel queasy.

I thought that perhaps if the sky was truly free of clouds and any other distractions (birds, kites, skywriting), we could see if there was something else out there. I wasn't really raised in any religion (in England I attended an Anglican school and went to a Methodist church, but I left that all behind at the age of eight when we moved to the U.S.), but like most people, I sometimes wonder if there's anything or anyone out there.
