You think when you walk out that door
  You'll never think about me anymore
  So sure that you got it all figured out
  
  You always forgot my birthday
  You never could remember my dog's name
  And there's one more thing you forgot
  
  CHORUS
  
  I'm not that easy to forget
  Someday you'll wake up and regret
  You ever let me get away
  I'll be on your mind night and day
  I'm not the kind of girl you leave
  And simply walk away scot free
  You don't believe it yet
  But I'm not that easy to forget
  
  I'm not gonna stand in your way
  I'll even help you pack your suitcase
  I wouldn't want to keep you from leaving town
  
  But as sure as you're crossing that line
  One day I'll be crossing your mind
  It'll hit you hard when the truth comes down
  
  REPEAT CHORUS
