[Verse 1]
You only call me when you're all alone
I don't know why I pick up the phone
I guess I'm lonely and you are too
This is the last thing I wanna go through
I wanna go through, through
I wanna go through, through

[Chorus]
It's a mystery, it's a mystery why you ever left
I don't know why, I don't know why I am second best

[Verse 2]
All that I wanted was a second chance
So I can convince you to take me back
I guess you're gone now, far away from home
And I'm just stuck here, confused and alone
Lone, confused and alone, lo-oh-one

[Chorus]
It's a mystery, it's a mystery why you ever left
I don't know why, I don't know why I am second best
It's a mystery, it's a mystery why you ever left
I don't know why, I don't know why I am second best

[Bridge]
All of the things
I never said
Run through my head
Run through my head
Run through my head
Run through my head
Run through my head
Run through my head
Run through my head
Run through my head
Run through my head
[Chorus]
It's a mystery, it's a mystery why you ever left
I don't know why, I don't know why I am second best
It's a mystery, it's a mystery why you ever left
I don't know why, I don't know why I am second best
