One of my students, who has now become an instructor, when he lost his vision, after a few months he was sitting in his three story house and he realized that he could hear everything going on throughout the house: conversations, people in the kitchen, people in the bathroom, several floors away, several walls away.
یکی از شاگردانم، که حالا خودش مربی هست، هنگامی که دیدش را از دست داد، بعد از چند ماه او در خانه سه طبقه‌اش زندگی می‌کرد و متوجه شد که می‌تواند همه صداها را در خانه بشنود: گفتگوها، وجود افراد در آشپزخانه، در حمام، چند طبقه دورتر و چند دیوار دورتر.
