[verse 1] D I'm not prepared for the future A So many things that I just don't know Bm I cut my hair, bought a new shirt, G new pair of shoes And it's time to go, D I finally found an apartment A Signed a lease on a car this month Bm I can't go back to the start now, G time doesn't slow down I'm on my own [chorus] D Guess my childhood is over Now I'm taking down the posters A And I'm putting all my things inside a box next to a toaster Bm That's my closest thing to closure I can't stop this roller coaster G I'm not ready to get older, I'm not ready to get older D Guess my childhood is over Now I'm taking down my posters A And I'm telling all my friends we'll get together next October Bm That's my closest thing to closure I can't stop this roller coaster G I'm not ready to get older, I'm not ready to get older [post-chorus] D Mmm, ba-ra-ra-ra-ra A Mmm, ba-ra-ra-ra-ra Bm G Mmm, ba-ra-ra-ra-ra [verse 2] D Never thought I'd be twenty A And thirty don't seem so far away Bm I know I gotta make a little money G then maybe find somebody To call my own D A Mmm, I'm not ready but I can't go back in time Bm G I know it's all out of my control now I know [chorus] D Guess my childhood is over Now I'm taking down the posters A And I'm putting all my things inside a box next to a toaster Bm That's my closest thing to closure I can't stop this roller coaster G I'm not ready to get older, I'm not ready to get older D Guess my childhood is over Now I'm taking down my posters A And I'm telling all my friends we'll get together next October Bm That's my closest thing to closure I can't stop this roller coaster G I'm not ready to get older, I'm not ready to get older [post-chorus] D Mmm, ba-ra-ra-ra-ra A Mmm, ba-ra-ra-ra-ra Bm G Mmm, ba-ra-ra-ra-ra [bridge] D Guess my childhood is over One day I'll be buying posters A for my kids just like my parents Did for me, it's never over Bm They'll grow up and soon enough they'll wish that time would just move slower G I'm not ready to get older, I'm not ready to get older [chorus] D Guess my childhood is over Now I'm taking down the posters A And I'm putting all my things inside a box next to a toaster Bm That's my closest thing to closure I can't stop this roller coaster G I'm not ready to get older, I'm not ready to get older [outro] D Mmm, ba-ra-ra-ra-ra A Mmm, ba-ra-ra-ra-ra Bm G Mmm, ba-ra-ra-ra-ra D I'm not prepared for the future A So many things that I just don't know Bm I cut my hair bought a new shirt G new pair of shoes and it's time to go
