Kite Flying

Very nice. I too like the bookends, particularly the way you've used it here, not merely to unify the poem, but also to show time's passage. The only line that did not work terribly well was "acrobat of air". Yes, it has assonance, but the "of air" seems redundant. "aerial acrobat" is smoother, but still, we know acrobats tumble in air. I'm not sure how to improve it.
