I can tell that you're not amused
  with the things that we used to do
  I remember that you used to be
  in the middle right next to me
  Think you thought it was time to leave
  must of thought you'd seen everything
  now your baggage is bitterness
  guess nothing was as sweet as this and....
    I'VE SEEN YOUR PAST IN FRONT OF ME
  I'VE HEARD THE WORDS THAT YOU'VE SAID
  YOU'RE NOT THE ONLY ONE AROUND WHO SEEMS SO SERIOUS AND
    I guess I really didn't realize
  friends of mine could be this way
  It's not your fault you had to change
  I just wanted it to stay the same and...
    I'VE SEEN YOUR PAST IN FRONT OF ME
  I'VE HEARD THE WORDS THAT YOU'VE SAID
  YOU'RE NOT THE ONLY ONE AROUND WHO SEEMS SO SERIOUS AND
    SO NOW I'M SITTING HERE IN DOUBT
  OF MYSELF
  YOU'RE NOT THE CAUSE OF IT
  DON'T FLATTER YOURSELF
    I'm really sorry that you seem to feel this way
  and I'm really sorry that you seem to feel this way
    I'VE SEEN YOUR PAST IN FRONT OF ME
  I'VE HEARD THE WORDS THAT YOU'VE SAID
  YOU'RE NOT THE ONLY ONE AROUND WHO SEEMS SO SERIOUS AND
    SO NOW I'M SITTING HERE IN DOUBT
  OF MYSELF
  YOU'RE NOT THE CAUSE OF IT
  DON'T FLATTER YOURSELF
    Sometimes I find it rather hard to forget
  some things you said weren't really that bad
  But it's a promise you made to me
  said the words and didn't mean a thing
