I like poems that leave me thinking, poems that start me thinking, I guess, and don't, at the end, tie everything up.
I guess I like puzzles. I like riddles. There are a lot of riddles in Emily Dickinson, for instance.
And I like space to think. That doesn't mean that I like to be vague. I hope I'm not vague.
I try to be very specific, but not everything that's specific is comprehensible.
