“Mark, 15 years old, enjoy camping and fishing. My little sister was born blind. I want to do my best to support her in life, but how can I teach her to live as a blind, if I don’t possess such a skill in the first place? Not to mention how being able to perceive the world in the same way, facing the same everyday difficulties is important for mutual understanding. So that’s what I’m here for. Where do I sign up for the blindness class?”
