What Am I?

What am I to you, or who,
Am i supposed to be?
When you ask me if I'm working, 
Are you asking if I'm free?

Are you asking for my company,
Or for what i can do for you,
In a professional capacity?
I just don't know what to do.

Occupied

Yes, Mr Crackhead,
I know that you're rattling.
I know that you're desperate,
But there are other things happening. 

This cubicle is occupied,
And I'm trying to shit.
And as soon as I'm finished, 
I'll be out in a bit.

I'd be much quicker you see,
But I have to implore:
That you stop knocking and shouting,
Through this clearly locked door.
