Maybe this is part of the definition of "askhole," but it drives me crazy when someone sees some success I had or some experience I got and asks advice, I explain what I did to succeed or what I did wrong and wouldn't repeat, explain how and why my advice really pertains to their situation, but it's not what they wanted to hear so they do the opposite. Then that often compounds by asking again, running the same sequence, and again doing the opposite of what was just explained by facts, logic and experience. The third time the answer is usually "I don't know."
