Yeah, that part about it being the "hard right thing" is so true. I had to talk to my neighbor about his sketchy outdoor outlet last year. I just went over with a couple of beers and said, "Hey man, I was grabbing my hose and noticed that cord looked fried, it really freaked me out." Framing it like I was worried for him, not judging him, made all the difference. He actually thanked me later because he had no idea.
Wait, did you really think about not telling someone? I mean, I've been in that spot, fretting over friendship, but bad wiring is serious business. My cousin had a close call with his garage wires last summer, and it woke me up to the risks. You have to look past the awkward talk and see the real danger. If a fire starts, your friend's shed isn't the only thing at stake, it's the whole neighborhood. So reporting it isn't about being a bad pal, it's about doing the hard right thing.
