A job in a 1920s apartment building made me stop trusting every 'standard' wiring diagram I see.

After that 1920s job, I always double-check with my own voltage tester first.

Come on, trusting your own tester over the prints is how mistakes happen. The diagrams are usually right, and second-guessing them just adds time and confusion. Maybe that one old building was the weird exception, not the rule.
