We know it's a buggery installation to the condition of human, but here it is, fervid and frazzled,the green glowering vein of jealousy.
Some ration it by diagnosing it at it's roots. It's merely our biological will to proliferate our genetics, "Mate guarding" they will call it.
But I fail to see how  this is anything but capricous as instead of helping me carry along my genetic line jealousy warps it into a suitable noose to adorn my neck.
Jealousy is simply an insatiable itch that flares up to feed my insecurities when they fall all too silent.
After all what good did security ever offer me?
