I asked this specific question CW because someone asked me why I had asked a question. I told him I asked it because it occurred to me. Those are the only kinds I can ask. I mean isn't it a no-brainer? Isn't the answer obvious? Now if his question had been "why did asking that question occur to you" I'd have say I don't know. I don't plan ahead for questions to occur me. They either do or don't and I don't question why. Thank you for your reply and Happy Thursday! :)
