Good lord.......

If you get too scared just cover your eyes with your skirt......but if things get really hairy just flail wildly with your purse, that should do the trick.
If you still can't take it, just crawl into the fetal position and sob softly until it's light enough to see where you threw your purse.

Now if your worried about some knucklehead shooting you in the dark by mistake, just make sure you have some sort of flashlight on (Those LED stylus lights are great).

Otherwise, suck it up.........there's no crying in hunting.
