All I want to say, really, is how much I love this poem—the way it moves between perspectives: the child looking at the adult looking at the child, and the adult looking at the child looking back at the adult in his ‘remoter heaven’. ‘Life is still asleep’: such a beautiful, poignant, wistfulness about that sense of promise which, given the double perspective achieved in the poem, is at once achingly long-lost and, wonderfully, still to come.

Altogether, a very ‘the afternoon knows what the morning never suspected’ sort of a poem.
