"I don't know what the earth looks like from the sky, I don't know what the moon looks like when you walk on its ground. I don't don't know what a Chinese panda really looks like, what it eats...

I don't know why the tall men use cars, when they have bicycles that do so much less harm to Mother Earth. I don't know if we are all alone in the great cosmos. I don't know what's in my body, what a germ looks like... And... why is it raining?

See, there are so many things I would like to know... and you, what don't you know?"
