Recently I decided to replace a ceiling light fixture with a ceiling fan in my computer room. Instead of turning off the power at the breaker, I just shut off the light switch and got to work. I changed the box and was finishing up the electrical work when a storm passed over outside. The storm darkened the room a bit, but I could still see fine to complete the job. Just then, my wife came into the room to help out. I asked her to hand me some parts and then she said, “Why are you working in the dark?” Taking matters into her own hands, she instinctively turned on the light switch and sparks flew from my screwdriver. Thank goodness my hands weren’t touching the wires. Next time I’ll turn off the power at the breaker!
