A mute man goes to buy a toothbrush. by miming the action of brushing his teeth, he shows what he wants. then a blind man wants to buy sunglasses, how does he indicate what he wants?
If he's blind he can speak he just can't see so I'm going to say this is a kind of question to trick question.The blind man is going to say he wants sunglasses he doesn't need to "SHOW" anything.
