“... a rhetorical question. It has a question mark at the end, but you are not meant to answer it because the person who is asking it already knows the answer.”
“Asking a question simply implies that you already know the answer. However, the question that you are asking may simply be an illusion. The beauty of the answer truly blooms, when you ask the right question.”
“The answer is already no, if you don't ask the question.”
“He who knows all the answers has not been asked all the questions.”
“I’m sick of asking questions everyone else already knows the answers to.”
“It isn't the sort of thing you ask questions about, because the answers are not usually answers you want to know.”
