I’m sitting in my darkened room
Engrossed in my old friend
Who I have not spent much time with
But now school’s at an end

I dance with her through thorny roads
We fight and then make up
I love her in a such dear way
I have her on a cup

It started out so simple too
Just me and her alone
My parents set me up with her
With her I’m not alone

We go back through a dozen years
To mother she is dear
She could have saved the Romans if
They only had her near

But who is this of whom I speak
I don’t think that I’ll tell
But if you caught “Getting Old“‘s bit
Then that will be your hint
