For Good

At last, I think I have found the song I've been looking for, for years. So many songs are about romantic love. There are hardly any songs about the beauty of platonic love. Now (actually a while ago, but it's come back to me recently) I have found such a song - For Good, from the musical Wicked. Other than this song, I can't think of any good songs about the joy and significance of a friendship. Here is a Youtube link, and below are the lyrics.

ELPHABA:
I'm limited
Just look at me I'm limited
And just look at you you can do all I couldn't do
Glinda,
So now its up to you
For both of us
Now it's up to you

GLINDA:
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 dont 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.

ELPHABA:
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 from what I learned from you
You'll be with me like a hand print on my heart
Now whatever way our stories end
I know you have rewritten mine
By being my friend

Like a ship blown from it's mooring by a wind off the sea
Like a seed dropped by a sky bird in a distant wood
Who can say if I've been changed for the better?
But because I knew you

GLINDA:
Because I knew you

BOTH:
I have been changed for good

ELPHABA:
And just to clear the air, I ask forgiveness
For the things I've done you blame me for

GLINDA:
But then I guess we know there's blame to share

BOTH:
And none of it seems to matter any more

GLINDA (ELPHABA):
Like a comet pulled from orbit
(Like a ship blown from its mooring)
As it passes a sun
(By a wind off the sea)
Like a stream that meets a boulder
(Like a seed dropped by a bird)
Halfway through the wood
(In a wood)

BOTH:
Who can say if I've been changed for the better?
I do believe I have been changed for the better

GLINDA:
And because I knew you

ELPHABA:
Because I knew you

BOTH:
Because I knew you
I have been changed
For good
