The Human Question

Why are people born with talents in art and music?  Why are people driven to create stories great and small?  Why are people curious about how the universe works?  Why do people decorate themselves and everything around them?  Why do they kill each other?  Why do they perform heroic deeds of self-sacrifice?

And why does Fiorella ask questions like this rather than chomp on a tasty piece of grass out there in the meadow?
