One that I especially like is Tech Support Cheat Sheet. Some people do seem to think that just because one has basic problem solving skills and exploits the reversibility of most actions that one is a computer expert.

Perhaps she thinks it's better not to know. As the saying goes, "when ignorance is bliss, 'tis folly to be wise". Or maybe she's looked under too many rocks in her life and found all sorts of disgusting things, so has learned not to look under rocks.
I once read an interesting novel called Rue des Boutiques Obscures [The Street with the Dark Shops, by Patrick Modiano] about a man with amnesia who by happenstance gets a clue as to who he really is. For the rest of the book he tracks himself down, and discovers something so heartbreaking that it would have been better if he had never known.
