There was a blind girl who hated herself just because she's blind.
She hated everyone, except her loving fiance.
He is always there for her.
That blind girl said that if she could only see the world, she would marry her fiance.
One day, someone donated a pair of eyes to the blind girl and then she can see everything,
including her fiance.
The fiance asked her, "Now you can see the world, will you marry me?"
The girl was shocked when she saw that her fiance is blind too, and refused to marry him.
Her fiance walked away in tears, and later wrote a letter to that girl saying
Just take care my eyes, dear
Moral: This is how human brain changes when the status changed. Only few remember what life was before, and who's always been there even in the most painful situations.
