Time and distance sometimes do not make the heart grow fonder, as they say. I've had friends who seem more of strangers now and it does seem like a long time ago, like a different life even, when I think of them.
The voice you used here seems laden with regret. There are sighs and painted clouds all over this poem, and you've created them in a way that isn't too much. There's balance, plus, I adore your ending. The creativity!
