actually this is not the first time that i have the idea, but i've never really tried it seriously. recently i learned something about deaf people in my linguistic class and i was shocked, more accurately, i feel kinda shame. when i was flattered myself that we are more healthy and capable than them so we should live a better life, they already refused to be called disabled. most of them live better than we are, and they consider sign language the most beautiful language in the world. instead of being hearing, they choose not. even though this is passive choice, but think this way, which one of us can possibly choose being tall or short, black or white, Chinese or American? that's the same thing. so keep your hands up and do the magic.
