To Be Honest I Really Don't Care

"I've Seen It All"
Bjork



I've seen it all, I have seen the trees,
I've seen the willow leaves dancing in the breeze
I've seen a man killed by his best friend,
And lives that were over before they were spent.
I've seen what I was - I know what I'll be
I've seen it all - there is no more to see!
