Too Fast

I always new one day I had to grow up, But I didn't think it would be so fast, When I was a kid I was happy, Now that I am older I am sad, As a kid I learned lessons, I learned my ABC's and 123's, I learned lessons not many kids learn, Lessons that are learned as adults, I learned how to get hurt, but I really couldn't help learning that, How fast a family can break, I found out about betrayal, and how easy it is to cheat on people, But mostly I learned how hard it is to grow up, All kids don't learn these lessons, and they are lucky they don't, When you learn these lessons it makes you grow up, Even if you don't want to, Pain is a lesson of an adult, When you learn it as a kid it can hurt even worse, You know when you've learned adult lessons you're all grown up, Trying so hard to stay a kid, We all know one day we have to grow up, but I didn't know it would be so fast
