I Knew You Were Trouble - Taylor Swift

Once upon a time, a few mistakes ago
I was in your sights, you got me all alone

You found me
You found me
You found me

I guess you didn't care, and I guess I liked that
And when I fell hard, you took a step back

Without me
Without me
Without me

And he's long gone, when he's next to me
And I realize the blame is on me

Chorus
'Cause I knew you were trouble when you walked in
So shame on me now
