A dumb person is leading a blind person to a shop . The dumb person requires a tooth brush. He signs to the shop keeper as if he were brushing his teeth . Now the blind person wants a comb . What action will he do ?
Precisely . CONGRATS . A blind man cannot see, but he can very well talk . So he can orally ask the shop keeper for a comb . When I put this question to my friends and relatives , most of them showed by sign ,as if they were combing their hairs . You too can try this with your friends .
