Hello, it's me, I was wondering
If after all these years you'd like to meet to go over everything
They say that time's supposed to heal, yeah
But I ain't done much healing

Hello, can you hear me?
I'm in California dreaming about who we used to be
When we were younger and free
I've forgotten how it felt before the world fell at our feet

There's such a difference between us
And a million miles

Hello from the other side
I must've called a thousand times 
To tell you I'm sorry, for everything that I've done
But when I call you never seem to be home

Hello from the outside
At least I can say that I've tried 
To tell you I'm sorry, for breaking your heart
But it don't matter, it clearly doesn't tear you apart anymore
