the blind narrator remarked that the face of the girl, his fellow passenger, was interesting.
the narrator wanted to conceal his blindness from the girl and with that intention, he complemented her by saying that She had an interesting face. the narrator was unaware of the fact That his co passenger Watch also blind. he tried his level best to prevent the girl from finding out the truth. therefore the remark was quit daring to him.
It was a safe remake as flattery was a thing not many girls could resist. the girl in response laughed pleasantly and said that the Meditos remark was nice to hear as she was tired of hearing her face being pretty.
