That old electrician who told me to slow down actually saved my butt
I was swapping out a panel in a 1920s house in Tacoma, rushing to beat the rain. The homeowner's uncle, who did this work for 40 years, watched me for a minute and said 'you're gonna bond that gas line before you touch the meter, right?' I laughed it off and said I had it covered. Turns out he was right, the ground wire was corroded behind the drywall and I would have missed it if he hadn't pointed it out. You ever had an old timer catch something you walked right past?
