Lol. Siblings. So which one of us is older than? So are you my big or little sister? Does that mean wet willies and headless barbies? Or do I have to be nice? :)
Why can't they be invisible, ever think of that? No you didn't, didn't think, "oh maybe he's sensitive about his invisible eyes". Maybe it's a skin condition. :P
I will admit, souls might be KINDA useful. Maybe. I still think they are overrated. I know many a beautiful soulless being that still somehow seems to capture my attention, even be it just for carnal reason. I suppose beauty is in the eye of the beholder though.
