I'd say I've read this one at least 50 times on 10 different days. I think that all but the first few words are perfect.
I find the SOON, and the the last stone WAS found
it's fascinating, like you are stepping into a time warp where the projected future and the past are concurrently inhabiting what is not possible.
At some other point I may actually talk about the rest of the poem but, I really like how that particular phrasing gives me the sense of someone who might spend time around archeological digs, speaking to themselves, of themselves- in that way it's thoroughly haunting, like they might be describing their own death, the thought pointing to a lack of life and therefore, it makes everything else most relevant. I like the thought that that phrasing and or - glitch was like a secret window to the poem and to me, that 'Soon,' represents the last stone.
Honestly, I don't think I have come across anything that strikes me with such utter sadness. She has sealed herself in.
