Take a couple of minutes to think about fire. It warms us up, but it must be fed constantly. Left to itself. it consumes all that it touches and soon dies. It can rage uncontrollably, and it is completely unpredictable. It has no body or weight. We cannot get too close without being burnt. It can never stand still. Once started fire'll go where it pleases and stop for nothing (well... almost nothing, but that's where the other elements come into things)
Fire, a sudden urge to do things, to live and breathe and just BE. To murder and create, to jump out of your skin and do things on the spur of the moment. To fall in love, to get into a fistfight, all manner of things that happen on impulse and soon die out. Fire.
