There was a blind girl who hated herself just because she was blind. She hated everyone, except her loving boyfriend. He was always there for her. She said that if she could only see the world, she would marry her boyfriend.
One day, someone donated a pair of eyes to her and then she could see everything, including her boyfriend.
Her boyfriend asked her, "now that you can see the world, will you marry me?" The girl was shocked when she saw that her boyfriend was blind too, and refused to marry him.
