You swing the door open and it's a long tunnel to some wonderous sun lit opening.
Quickly your mind is made up and through the door you go as it slams shut behind your step. You turn to find this is a oneway only as there is no knob to reopen this door. Your head falls as chin touches your chest, a sudden feeling of personal sorrow as what ever is to come is now certain.
One step and then another as with moving toward the far away end of this tunnel your spirits build and the hope of freedom boils in your soul.
The opening is getting larger and the cool air and sunlight seems to fill the tunnel. Your walking has turned to a jogging as that hope of freedom building inside yor chest is giving you warm feelings of delight.
"Yes, Yes this must be the way out!" you say to yourself.
Then bonk, your face, chest, and right knee slam into a angled mirror.
The tunnel has a T angle, either right or left yet both ways reflect in the mirror and both show the same scene outside the tunnel.
"Which way?" you look and wonder right or left what is the reason for this obvious choice. A choice which must do something otherwise this turn would not be here, and to what will this turn do to me? All this you think as that cool freshness lures you on.
