Eleanor Rigby picks up the rice in the church where the wedding has been
Lives to be clean
Waits at the window,wearing the teeth that she keeps in a jar by the door
Who are they for?

The story:

I thought the song was about a sad, lonely, toothless old woman who had some kind of a germ phobia. I was finally disillusioned when I heard the song properly while driving. Fortunatly I was alone. Sad, lonely and alone. At least I still have my teeth.
