Birch trees

What could a birch tree be, except a girl?
A young girl, poised on the edge of a dance
with her arms wide, and her hair uncurled,
loose round her shoulders; and her friends
clustered around her, whispering secrets,
rustling and murmuring in their pale dresses,
telling each other which bird did this,
and what the squirrel said. Nobody guesses
how much they see, the supple birch trees,
that sway as they wait, feeling the notes
sung by the robin, played by the breeze –
they can’t resist. Even when they’re old
they sway like that, to music half-forgotten,
melodies half-heard, echoes of rhythm.

This is for Grace at dVerse, who is asking us to use imagery and/or personification. there is, of course, a nod to Robert Frost here, and I’m still wrestling with the sonnet form. The rhymes got pretty slant-y in this one.
