I'm going blind in my left eye. So far it's temporary. I wake up and can only see white in one eye for about twenty minutes, then it passes. No one knew until I heard a sound, turned to my left and whacked my head. Hard. I'm more careful now.
Sam went mostly blind. Permanently. Well, first she went deaf. At first, no one knew. They just thought she was getting pig headed in her old age. She was twelve, and a lab, like me. When she responded to hand signals, but not words, they figured it out. I don't really know hand signals. I guess I'll be in trouble in five years.
