I was working at a motorcycle shop as a mechanic adjusting a carb with a special screwdriver. I blip the throttle a couple of times and go to tweak the idle air screw a bit and can't find my screwdriver. I search the bench the bike is on and then my toolbox but it's gone.I search the bike to see if I had laid it somewhere on the bike but no luck. Next I go to the sales counter to see if someone had borrowed it while I wasn't looking. I asked if anyone had seen my screwdriver and the secretary asked if it was the one in my hand. Sure enough I had been searching for about ten minutes for what I had been holding in my left hand. I would like to say it was from old age but I was about 20 at the time. Now if I don't put tools back where they belong, they are lost until I stumble on them.
