I always thought
If I’d the key
I’d open Door 13

Behind which
Lies the secret
Of the man I might have been

It’s up there
Lying somewhere
In the corner of my mind

The door
To some reality
That I could never find

The thrill of heart
I wanted
Out beyond this dull routine

The golden key
To show me
How to get past
Door 13
