You want it back, everything that you wanted to give to me At a point in time when you and I were fine, now you don't speak to me And I guess that's fine, your heart's not my responsibility But there was time when I felt like I wanted it to be But I can't say I don't care, I can't fix what's not there And if you're listenin' Let me say this loud without whisperin' Why don't you grow up, grow up? Should have known better Should have known you'd never Grow up, grow up Should have known better Should have known you'd never So take it back, everything that you once said that I could have 'Cause if you didn't mean it, then I don't need it, I'll leave it at your dad's Honestly, it's fine, I won't lose my mind tryin' sort this out I'm just a human bein', runnin' out of feelings, nothin' to talk about And I can't say I don't care, I can't fix what's not there And if you're listenin' Come on, please, we know you're listenin' Why don't you grow up, grow up? Should have known better Should have known you'd never Grow up, grow up Should have known better Should have known you'd never I don't feel sad, I don't feel bad I've not lost everything Still got so much, I don't miss your touch I don't miss anything Why don't you grow up, grow up? Should have known better Should have known you'd never Grow up, grow up Should have known better Should have known you'd never
