　　now hear this
　　what did you learn at school today
　　that's what the teachers used to say
　　but they don't know
　　don't understand, do they
　　why do they always give advice
　　saying just be nice, always think twice
　　when it's been a long time since they had a teenage life
　　what did you learn at school today
　　that's what the teachers used to say
　　but they don't know
　　don't understand, do they
　　why do they alwaya give advice
　　saying just be nice, always think twice
　　when it's been a long time since they had a teenage life
　　dwelling on the past, from back when i was young
　　thinking of my school days and trying to write this song
