Anne: So I decide to string lights on the stairs. I pull out some bundles and start untangling and plugging in to find strands that work.
Success! I find two strands!
I begin! And get ready to attach and plug in the next strand.
Crud! This strand was lighting but now isn't!
Aha! I see the problem!
My assistant looks innocently on as I try to find another strand that lights.
