1. I think part of the appeal of the poem is that it ISN'T very clear. You could be talking about anyone in many different contexts and it would still work. It depends on who's reading.
2. A choking sort of silence, when there are so many things that need to be said at all the wrong times to a person that is not there anymore. Terrible, heartbreaking quiet....one that echoes of both fear and regret.
3. I love how you can weigh your words in such a way that give even short poems a lot of clout.
I understand part of this - silence can be louder than words. Or have more impact. And I suppose people might think of my voice if I said nothing and saying nothing meant something. Interesting little verse. Nice work.
