Lost wisdom

I had a very strange dream last night. In my dream, I was reading (writing?) a story, and this is how it went:

"The Boy asked his Father (for his Father was a wise man, learned in all the ways of the world): 'Father, why are people so cruel? Why do they hurt each other so? Why do they persist in doing so, knowing it hurts themselves and others; especially those nearest to them, the ones they care about the most and the ones who care for them the most?'

"And his Father smiled, and sagely replied..."

At this moment, I inexplicably woke up, and try as I might, I couldn't go back and pick up the dream where I left off. And now, all I feel is a profound sadness, knowing that I've probably lost that nugget of dream wisdom forever.
