I am twenty years old today.
I know nothing.
I am thirty years old today.  
I know a bit, but not what I’m doing.

I am forty years old today.
What little I thought I knew… turns out it was wrong.
I am fifty years old today.
I know more than you sonny.

I am sixty years old today.
I’m tired of knowing.
I am seventy years old today.
I never appreciated people.
