To Evolenilec: "convoluted..." Not at all. You knew someone so fine, that when they left, it ached so bad, you couldn't stand it; you needed "somebody else" to fill that void. Anyway that's how I always felt about this song; for me, it spoke to a personal experience.
I find the message in this song convoluted. That is to say, I do not find the song all that romantic or loving. The words 'someone like you makes it hard to live without somebody else' isn't all that complimentary to a loved one. I wonder what 'Rod the Bod' was thinking when he wrote the song, perhaps he was talking about his previous pet. Duh?
