Hey dad look at me//Think back and talk to me//Did I grow up according to plan?//And do you think I'm wasting my time doing things I wanna do?//But it hurts when you disapprove all along//
   
And now I try hard to make it//I just want to make you proud//I'm never gonna be good enough for you//I can't pretend that//I'm alright//And you can't change me//
   
'Cuz we lost it all//Nothing lasts forever//I'm sorry//I can't be perfect//Now it's just too late and //We can't go back//I'm sorry//I can't be perfect//
   
I try not to think//About the pain I feel inside//Did you know you used to be my hero?//
All the days you spent with me//Now seem so far away//And it feels like you don't care anymore //
