My father was fixing an appliance while plugged into 220 and has the skin grafts to prove it. My mother enjoyed telling the story of having to beat at him with a broom to get him to let go of the screwdriver because of galvanic reaction.

When the dogs were getting into my mom's irises he put up an electric fence. He bought it off a ranch. It was intended for cattle. Me and my friends discovered that if you grabbed a piece of grass and touched the wires the grass would burst into flame. Then my 4-year-old sister grabbed the fence with both hands and shook like crazy. Apparently coursing 110v across the heart of your daughter was considered a bad enough idea that the electric fence got turned off. At least, until she turned ten. Then it got redeployed to try and keep the new dogs from jumping the new fence.

I ended up with a cavalier attitude about electricity as a consequence - if it isn't 220, it isn't dangerous. I'm still a lot more likely to flip the breaker to fix something if there are people watching. If there aren't, I'll probably wing it.

It's probably a good thing I got out of electric cars.
