Took it all from me when I was only 17 I kept you close where I could see but now I'm blind And every, lonely night I check my phone for your reply I'm feeling things I can't describe, in my mind But when the days turned dark I'd walk you home We'd stay out late we'd lose our phones I'd feel at one when we are on our own If I'd have known that night That you'd come in and you would change my life I don't know what you did but you did it I don't know what you did but you did it Can never take it back The part of me that you've detached I blame myself believing that We'd be fine But when the days turned dark I'd walk you home We'd stay out late we'd lose our phones I'd feel at one when we are, on our own If I'd have known that night That you'd come in and you would change my life I don't know what you did but you did it I don't know what you did but you did it Oh, if I'd have known that I Don't think I ever would have left that night 'Cause I don't know what you, did but you did it I don't know what you did Oh, and when I pull it all apart I see that you've been with me, from the start You open up the light that dims the dark All from your heart If I'd have known that night That you'd come in and you would change my life I don't know what you did, but you did it Said I don't know what you did, but you did it Oh, if I'd have known that night That you'd come in and you would change my life Oh, 'cause I don't know what you did, but you did it I don't know what you did, but you did it Oh, if I'd have known that I Don't think I ever would have left that night Oh, 'cause I don't know what you did, but you did it, yeah I don't know what you did What you did but you did it
