This Prisoner’s Dilemma

Locked up but the door's open 
Prison's cosy; familiar territory 
Rules, duties, obligations; noted 

Bed by the window, view is great 
I see an inmate unlike myself 
The walls of their cell; a different colour paint 

My warden seems pretty nice, gets me everything I like 
Promised to take care of me, if I stay inside these walls 
The door's open; I'm locked up

So I keep busy, I read books 
Toy with these gifts, spy on my neighbour; the tree 
Her leaves blow in the wind; I smile. 

I've been in here all my life, that's a long time 
Sometimes I'd like to go outside, see what it's like 
Go through the open door; sit under my neighbour's shade

The warden won't let me, says it's not wise 
Chains my arm to the bed and snuffs out my light 
Knows that I'm afraid of the dark; I'll scream all night 

Leaves the key at my bedside and the torch by my window
Says I have one choice; light the torch so I don't lose my voice
Or unshackle myself and run into the moonlit night

The warden smiles, walking out the door
Shouting goodnight and I'll see you tomorrow
Even though we both know; this door's open wide.
