I don't know where I went wrong Playing back memories every night And I don't know how to move on Knots in my stomach tied too tight Years pass and my hands get colder Hair turns grey and my heart beats slower Now the weight of the world's on my shoulders 21 and i'll say it til it's over I don't wanna grow up I just wanna get drunk with my friends And laugh a little too much As soon as it happens the faster it ends Wasting my time tryna press fast forward Spending my life wanting to be older But now i'm on the run And I don't wanna grow up You kept me close like a promise Hearing your heartbeat every night And I would sleep in your t-shirt Do you still sleep in mine? Years pass and my hands get colder Hair turns grey and my heart beats slower Now the weight of the world's on my shoulders 21 and i'll say it til it's over I don't wanna grow up I just wanna get drunk with my friends And laugh a little too much As soon as it happens the faster it ends Wasting my time tryna press fast forward Spending my life wanting to be older But now i'm on the run And I don't wanna grow up So i'll never grow up and i'll stay the same Say i'm 21 til my dying day I'll pretend that my friends won't drift away Cause it's better than being alone I don't wanna grow up I just wanna get drunk with my friends And laugh a little too much As soon as it happens the faster it ends Wasting my time tryna press fast forward Spending my life wanting to be older But now i'm on the run And I don't wanna grow up 21 and my hands get colder 21 and my heart beats slower 21 got the world on my shoulders 21 and i'll say it til it's over
