It depends on when I listen to the song I guess for example every year I volunteer for a camp for Kids who have cancer (their siblings go to the camp as well) at the end of the week everyone involved with the camp watches a slide show from the week and no matter what this song brings everyone to tears.
Also this song is very sad "Keep me in your heart for a while
This song is tragic (to know why you have to know the story behind it) also because the singer is a good friend of mine (Sean Kelly wrote this after His girl friend was killed in a car accident. He was waiting or her to arrive for a very special date he was to propose to marry her. She was on her way to the date when a driver ran a red light)
