You want it back, everything that you wanted to give 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 a 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?
Shoulda known better
Shoulda known you'd never
Grow up, grow up
Shoulda known better
Shoulda 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' to sort this out
I'm just a human being, runnin' out of the 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?
Shoulda known better
Shoulda known you'd never
Grow up, grow up
Shoulda known better
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
Shoulda known better
Shoulda known you'd never
Grow up, grow up
Shoulda known better
Shoulda known you'd never
