The song is about unfulfilled attractions, saying that they 're normal and commonplace ("We want everyone -- no one ever is to blame ''). It uses a number of metaphors, such as "You can look at the menu, but you just ca n't eat '' and "It 's the last piece of the puzzle, but you just ca n't make it fit, '' to describe the frustration of experiencing attraction but being unable to act on it, for whatever reason. On a deeper level it describes the frustration and pain of unfulfilled desires and dreams inherent in the human condition.
