I hate it when people ask you a question and then stop in the middle, leaving the meaning of the question – and more importantly – the assumptions behind the question, open to interpretation. I hate it because it’s lazy and it’s rude. It offloads the task of precisely formulating the question by filling in the missing pieces to the person you’re asking. I tend to get very frustrated. Most of the time I will give a short yes or no answer. The answer will be correct for the question as stated, even though I might answer the opposite if I took the pain of fixing the broken question. When the vagueness is such that such an approach isn’t even possible, I’ll tirelessly keep repeating that I do not understand the question, please reformulate. Unfortunately, the people most prone to this type of question asking don’t get the hint.
