Sometimes I wonder about my life. I lead a small life. Well, valuable but small. And sometimes I wonder, do I do it because I like it, or because I haven't been brave? So much of what I see reminds me of something I read in a book, when shouldn't it be the other way around? I don't really want an answer. I just want to send this cosmic question out into the void. So good night, dear void.

You're a lone reed. You're a lone reed, standing tall, waving boldly in the corrupt sands of commerce.
