Aww...
Fun story time!
A few years back, I was doing some body work on my car... actually, repairing old, bad body work.
A couple years before that, my sister had been driving the car (and was actually in a funeral procession) when a car behind her lost its brakes; the driver decided that instead of rear-ending one car, she'd straddle the lane marking and ping-pong between the two lines of cars, doing body damage to a whole bunch of cars, including mine. We found out later that the body shop we took the car to just slapped bondo on over the dent without doing any prep work at all.
Anyhow, the bad repair was starting to crack and peel, so I decided to do it properly myself. The first step was grinding away all the bondo to find good metal to use as a base for the new repair. I was using a wire brush in an electric drill; the safety goggles I was wearing had a strap that hung down a bit too much, and I was way too focused on my grinding... and, well, I snagged the strap on the wire brush. In a flash, the strap wound around the shaft and the drill and wire brush suddenly zipped straight at my face, cracking my goggles and cutting a nice gouge out of my cheek. I wrestled with the drill for a while (which was still turned on, and still trying to get closer to my face) until I could get a hand free to unplug it.
So... besides the fact that this is the only instance that I know of where safety glasses actually
caused an injury, I guess the point is that
everyone has episodes of clutziness.
