There was a girl With the toughest of skin She made sure that everyone around knew that she wasn't sensitive She walked around Let nobody in Thought if she never give her heart away it'd never end up broken But boy x across the street, oh, he was one of a kind Made her fall in love with only just a look in her eyes When they wandered off to someone else's for the first time She cried and cried and cried Next time you move on Like I know you'll do Tell me you won't treat her like you did with me and you And when she falls hard And a little too soon Promise you won't promise things you know just won't come true And don't you dare make her feel like she's the only thing you're seeing No, don't do that stupid thing with your eyes unless you mean it When you get bored Like you always do Tell me that you'll let her go Before you look for someone new Yeah, this very girl Brown eyes and blonde ends No, she never wasted time but time with him just felt so different She wrote him songs Just to watch him listening A hundred songs a couple months in No, she never saw it coming Next time boy x, he crossed the street, she'd never see him again She really thought he was forever, then forever was dead Left her holding up the pieces of her heart by a thread He left her there to die Next time you move on Like I know you'll do Tell me you won't treat her like you did with me and you When she falls hard And a little too soon Promise you won't promise things you know just won't come true And don't you dare make her feel like she's the only thing you're seeing No, don't do that stupid thing with your eyes unless you mean it When you get bored Like you always do Tell me that you'll let her go Before you look for someone new There was a girl Not too different from me She thought she found her world But then the world found out she's weak I guess that's okay No, I just couldn't see That there's a billion of boy x But babe, there's only one of me
