You'll get hooked, you'll get drugged  
  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
