This is all that matters now And that was all that happened anyhow You can look back but don't stare Maybe I can love you out of there

And when I went away what I forgot to say Was all I had to say: Eight letters, three words, one meaning

And outside forces didn't make it easy So I thought I'd go before you leave me Self-preservation was no explanation for anything
