Well I never really cried over a song  but thisone mademe super sad its kinda long http://www.youtube.com/watch?v=tzNY6HZ9edo its about a photographer that falls in love with this girl and when they are in the room where his pictures are procesed she acidentaly poors liquid on her eyes and that makesher blind. The guy cant standit so mutch he gives up his own sight to give hers back keep in mind his job requires him to see things, so he basicly gives up his whole life so that she can see.
