""If you could go back in time
When I was yours and you were mine
Would you change a single thing
Or let things play out as they did?
You don't know, you don't know
You don't know how this will end
'Cause we can't buy what the future sells
Or trade on what the past has dealt
They say we grow as time goes by
I always thought that was a lie
'Cause I ain't learned a single thing
I keep repeating everything
And I don't know, I don't know
No, I don't know how this will end
'Cause we can't buy what the future sells
Or trade on what the past has dealt
I'm taking more pills than advice
I feel like shit, but look alright
And I ain't heard what you've been saying
But at least I killed the pain
And I don't know, I don't know
I don't know how this will end
'Cause we can't buy what the future sells
Or trade on what the past has dealt
Maybe one day we'll break through
And we can start it up brand new
But I don't know how this will end
All I know is that it will
And I don't know, I don't know
I don't know how this will end
'Cause we can't buy what the future sells
Or trade on what the past has dealt
No, I don't know, I don't know
I don't know how this will end
'Cause we can't buy what the future sells
Or trade on what the past has dealt
No we can't buy what the future sells
Or trade on what the past has dealt""
