I know this girl, she's always on my mind
  She lives in her world and I live in mine
  I should forget about her and I've tried
  Lord knows I've tried
  But I want to know her, and here's the other side
    I've got someone waiting for me every night
  She's the only one I've ever loved
  And it's been that way for the longest time
  She's the one that makes my world go right
  And it tears me in two because I know where I'll be tonight
    I think she knows it
  I think she knows
    Two different worlds, two different worlds
  One that belongs to me, one could be wrong for me
  Two different worlds, two different worlds
  Oh, two different worlds
    Is she that different or is it the thrill of someone new
  Strung out on her, I need her love
  I need it bad, and I know, I know it's true
  I'm the one that lies awake alone
  I know, she's the one that makes me stray from home
    And I know it
  Yeah, I know it
    Two different worlds, two different worlds
  One that I may regret, one that I can't forget
  Two different worlds, two different worlds
  Oh, always two different worlds
    No, I can't explain this emptiness
  No, I know I can't go on like this
  Two different worlds, two different worlds
    Two different worlds
  I live in two different worlds
  One that I may regret, one that I won't forget
  Two different worlds
  But I can't live in both, I know
  One world I must let go
