I asked myself – why it's always like that, why we always really appreciate something after we lost it, for a while, or even for ever? Why we can deeply appreciate "the way green feels" – whatever it means in our lives, only after we spend some time in the desert – whatever it means in our lives, as well. And the only explanation I find (for now?) is that – if everything would be continually so intense like "green" in this haiku, in our life, maybe it would be too hard, even impossible, to stand it? Maybe.
