in korea they say that the sky gets "higher" during autumn and it makes everyone wistful (some would say "beige" :) ) and filled with a longing for love. there must be something instinctual about love=warmth i suppose? *shrug*
autumn, to me, always feels like staring desperately out the back window of your parent's car (Holden Kingswood in my case) after they've picked you up from your Best Summer Holiday Ever, willing with every fibre for it not to be over, while knowing you are heading back to your Worst Nightmare Ever (girls boarding school in my case).
anyway here's crunchy brown leaves, high skies, wistfulness and lots of love-warmth (which is very eco-friendly after all i suppose, so gets two thumbs up from me)
