I don't mind. You're not being as nosy as those bloody reporters sniffing about, at least, and I don't mind sharing the basics.

I don't know about getting better sight. I did receive some magnifying lenses, so perhaps not, I shouldn't need such a thing if I had sight enhanced the same way my hearing and sense of smell is. I mostly sleep with earplugs, though I am getting used to the noise, rather the way one gets used to sleeping with a fan or a computer on, for example. That might help you, as well, having some kind of white noise in the background :)

I do change completely. I actually can change completely into a wolf at will, any time after sunset and before dawn, but the only time I'm dangerous is the full moon. That's why I leave, or else keep myself locked up with guards on the door, just in case. When I leave, I only change a little, but I bring a friend with me who can keep me contained regardless, just in case.
