Y'know what really makes me happy? Innocence. There's something about the lack of knowledge that makes Innocence so...fond. Probably because as we grow older, we learn a bit more about ourselves and the world around us, and we slowly lose our innocence as we learn more and more. That's the sad part about innocence: We can't ever get it back(unless you believe in re-incarnation, then MAYBE). Keep it while you can, if you so wish to.
