While debugging an application I often repeat the same thing three or more times, because I'm not 100% sure I'm doing it exactly the same way. And I think that it's often very hard to define "the same thing". And that's the magic behind problem-solving for non-technical friends: they already tried the same thing, "why does it always work when you try it"?
