Light Switch? Bah!
I`ve accidentally left lights turned on in basements and attics following my testing of the fire detection equipment on those places, and got a real b*ll*cking over it from the caretakers (janitors). So, now, to minimise that occurence I rarely look for that little flat plastic thing on the wall by the door, and reach for the 9N strapped to my overly ample waist instead. The only one who gets a little p!ssed at leaving
that one on is me, and years of highschool have taught me that I don`t matter.
Plus it`s more fun.
Oh, an interesting fact- the CSI guys might be on to a good thing blasting everything with M4s to find that obscure bit of evidence. A couple times now, I`ve dropped tiny irreplaceable terminal-screws on the floor, and my 9N (or M3) has found them again within seconds. No lite, no findy screw, and then the immediate need to replace a whole strip of terminals. Odd, that. They must put magic bulbs into these SureFires, I tell ya
I never leave home without at least two.
