 I think of a while ago, we might have had it all
 I was so stupid then, you needed time to grow
 But now just as things change, as well my fellings do
 In time things rearange, I am so sick of chasing...

  You, but what do I get 'cause I just seem to loose
  You make me regret those times I spent with you
  And playing those games, as I wait for your call
  And now I give up so goodbye, and solong

  It's not a change of pace, this time I'll get it right
  It's not a change of taste, I was the one there last night
  You had your other friends, they were there when you cried
  Didn't mean to hurt you then
  Best friends just won't leave your side
