There's a certain beauty to an L-shaped zone, it gives you chance to sit & contemplate, to think about your loved ones, how to face your fears, even count the ticks on your subdued wrist watch. You also learn about stillness, & how not to move, how not to arouse suspicion. It takes real guts not to squirm when beads of sweat roll down between the cheeks of your ***. 'Cause to do so would mean certain death, or at the very least, giving up your position. And in enemy territory, doing that, ain't cool.
