D (xx0232@1)                          GbJust (244322@1)the other day she was a little girl
        GTaking (320003@1)over the world
         AWith (x02220@1)her smile

    D (xx0232@1)                           GbBut (244322@1)just the other day I saw that little girl
         GTaking (320003@1)a tongue down her throat
     A (x02220@1)                    GBy (320003@1)a boy that didn't give a damn
                  DThat (xx0232@1)she was only 15
                         A'Cause (x02220@1)she was more than willing

take a chance, 

To find romance, 

To grow up fast.

    G (320003@1)                   DBut (xx0232@1)I know she is so much better
                    AThen (x02220@1)to give it all away

To the first guy, 

First try, 

First lie, 
             DFirst (xx0232@1)goodbye.
