If a stupid person asks a question is it by default, a stupid question by then? I definitely believe in stupid questions.
If the question is a genuine question that you don't know the answer to, I feel like you should ask. If you're just asking to be stupid ? then it's obviously stupid.
Like you was so tired then your sibling ask you "back from work?" Your sibling actually ask the questions regularly and usually you will say, "yeah" but since you're really tired and 'stress,' you might say, "please don't ask me stupid question now."
