I don't care why I'm the way I am. I could blame society, my parents, my childhood, my accident, the area I grew up in, teachers, pets, the color of the rug in the livingroom of my aunt's house... but it doesn't change who I am to find out the reason why.
I think learning how you progressed in life is interesting. I think the workings of the human mind are fascinating. But when we get to the point of trying to pinpoint every action's cause... well that's where you spend more time analyzing and less time living.
I have no desire to stick a psychosis label on cding. It simply is. I was born with gray eyes (using the gorgeous Sheena's example). Sure I could find out the scientific reason behind it, but it doesn't change their color.
