From what I understand, Flash Ficiton is supposed to be short and spontaneous, so here goes:
It was a dark night in the mountains of Wherever. I was hanging off a cliff by my fingers, feeling the warm breeze of exhaust fumes. I wasn't in any trouble, I was just engaging in a favorite activity when everyone else has gone away.
What I like to do is drive my truck out to the edge of a cliff, back it right up to the edge, get out of the truck with it still running, and gently lower myself until I'm just dangling by my arms. Then I time myself to see how long I can stay like that, with the deadly carbon monoxide blowing in my face, until I chicken out, and climb back up, get in the truck and then leave. Of course, If the fumes knock me out or if I slip and fall, I'm toast - unquestionably dead.
I've never told anyone I do this mainly because I don't want competition. I've been able to hang for 15 minutes with one end of a torn garbage bag funneling the exhaust fumes straight at me. But I've got it down to a science. If I start to get dizzy, I turn my head so I can get a fresher breath of air. So far I hold the world record in this, and I don't want any challengers.
I think tomorrow I'll try it with a live scorpion on my head.
