Immaturity

Why can't you just act your age? Don't you know you're going to drive a car someday? Why do you always put on an act? When will there be a day when you develop some class? When high school comes around in just a couple of days You better do your work and get amazing grades Or else you'll be working at a job that's super lousy That's how life's gonna be If you don't snap out of your immaturity If you keep going on like this You're probably gonna be homeless Living on the side of a street And that's not what you want to be
