I think..

That the difference between video and audio is ...
the audio grows on you if you listen to it long enough, but the video is based on an instantaneous frame of mind.
So once you like a song, u can not unlike it, but once u like a movie, there is always a frame of mind when there is a distinct possibility of hating it.
Is it that we see, more than we listen ?
On the other hand, words dont hurt as much when u cant hear the tone.

Did you see the movie "The village"?
The blind girl has been so brilliantly portrayed. Her other senses, so acutely developed.
She didnt seem to miss her vision so much !
Maybe she can feel her nipple brushing against her muslin fabric a little bit more on those blustery windy mornings.
Or the touch of a rough hand on her pale face.

Maybe she can hear the ants walking.
or the wail of a cow being butchered far away.

Blessed are they that cant hear or see.
Away from life's misery.
