I wish I could write a letter to myself 'Cause I know I won't listen to anyone else At sixteen, your biggest dream is wearin' his letterman jacket You're so in love And breakin' up is the worst thing that could ever happen Then it happens And you're just too young to see That it passes Yeah, I know that He broke your high-school sweetheart And it feels like your life's over before it starts You think your whole world revolves in those hallways But it won't always You'll just have to trust me One day it'll just be high-school sweetheart (Sweetheart) If you could only see who you are now That quiet kind of confidence you've found One day, that boy will just be a black-and-white picture in a yearbook You'll hardly remember how He broke your high-school sweetheart And it feels like your life's over before it starts You think your whole world revolves in those hallways But it won't always You'll just have to trust me One day it'll just be high-school sweetheart (Sweetheart) Mmm, sweetheart I know you don't wanna hear it But you'll grow through the pain You'll find out one day That he wasn't the one anyway But, I know that He broke your high-school sweetheart And it feels like your life's over before it starts You think your whole world revolves in those hallways But it won't always You'll just have to trust me One day it'll just be high-school sweetheart (Sweetheart) Mmm, sweetheart Mmm, mmm, sweetheart
