I was this

I was that

I was—rat-a-tat-tat—

Who’s there?

Who’s knocking, oh

Welcome back Jack!

You are here

Door’s open

Let’s have a chit-chat

I am great

I am grand

I am—rat-a-tat-tat—

A friend?

Who’s there?

Who’s knocking at my nerves?

It’s me, your conscience

I am here to serve

You not what you have been

Or whatever you were

I am here as your guide

I am honest

I am pure
