For Good (From "Wicked")

I've heard it said
 That people come into our lives for a reason
 Bringing something we must learn
 And we are led
 To those who help us most to grow
 If we let them
 And we help them in return
 Well, I don't know if I believe that's true
 But I know I'm who I am today
 Because I knew you...
 Like a comet pulled from orbit
 As it passes a sun
 Like a stream that meets a boulder
 Halfway through the wood
 Who can say if I've been changed for the better?
 But because I knew you
 I have been changed for good
 It well may be
 That we will never meet again
 In this lifetime
 So let me say before we part
 So much of me
 Is made of what I learned from you
 You'll be with me
 Like a handprint on my heart
 And now whatever way our stories end
 I know you have re-written mine
 By being my friend...
 Like a ship blown from its mooring
 By a wind off the sea
 Like a seed dropped by a skybird
 In a distant wood
 Who can say if I've been changed for the better?
 But because I knew you
 Because I knew you
 I have been changed for good
 And just to clear the air
 I ask forgiveness
 For the things I've done you blame me for
 But then, I guess we know
 There's blame to share
 And none of it seems to matter anymore
 Like a comet pulled from orbit
 As it passes a sun
 Like a stream that meets a boulder
 Halfway through the wood
 Like a ship blown from it's mooring
 By a wind off the sea
 Like a seed dropped by a bird in the wood
 Who can say if I've been
 Changed for the better?
 I do believe I have been
 Changed for the better
 And because I knew you...
 Because I knew you...
 Because I knew you...
 I have been changed for good...
