Letra de Walls

I am a lost cause I built up these walls And won't let nobody through them I put up my guard You won't break my heart When you try to pick up the pieces Think of when we met You broke down my walls And gave up your heart to me It was enchanting to meet you I wish we could do it over And I would have never taken your heart And proceeded to break it Into a million pieces I am a lost cause I built up these walls And won't let nobody through them I put up my guard You won't break my heart When you try to pick up the pieces Kinda bittersweet How I would feel Resting my head on your shoulder I wish that you were older To break down my walls I made mistakes and now I can't undo them Broke my heart enough that I'm dying I think about you smiling I am a lost cause I built up these walls And won't let nobody through them I put up my guard You won't break my heart When you try to pick up the pieces
