She'll be your essence she'll be your blood
  And you'll want her so much but you'll never get enough
  And that's the first rule of love

  She'll smell so sweetly in the morning
  She'll make you feel so good inside
  And you'll want her so much you'll give everything else up
  And that's the first rule of love

  You'll grow comfortable together
  You'll start to fit like hand and glove
  And then you'll start to hate the men she used to dream of
  And that's the first rule of love

  You'll miss her madly, when you're apart
  Love is like gravity holding down your heart

  You'll grow envious and bitter
  She'll be enquiring and concerned
  And you'll feel so close to her but never close enough
  To get past the first rule of love
  And with the awkwardness of strangers
  You will finally give up
  No exceptions to the first rule of love
