Thank you for the responses.
LP, you're both spot on, and dead wrong. Don'tcha just love that? I write what I see in my head, and often, I'll use words that just seem to fit best, sound the most melodic, provide for wordplay, or all of the above. Being inherently lazy, I leave the interpretation to the reader, which can be a dangerous thing. *chuckle* In some other poems, the responses had me scratching my head on where they got that image, since it was about as far from my original image as could be. But still valid, nevertheless.
I do enjoy your critiques, as they make me think and second guess my own writings. Truth is, all I had was a picture of a large tree shedding leaves, them falling to the ground. Then I saw that the leaves were people and when I looked at the tree, the name 'Yggdrasil' crept into my mind, probably from my early fascination with Nordic, Grecian and Celtic mythology as a child. The leaves added to the leafmould and gradually sank into the earth as fertilizer. So too do people, when you get right down to it.
