If you were to ask someone a question with an obvious answer just to ask another question or to bring a subject up, would that be rhetorical? Like asking "Are you okay?" when someone is obviously hurt when you really mean "What's wrong?" or "How can I help you?". Or if someone at work is absent and you ask "Is [Person] out today?" when you really mean to ask why they're out.
I've been wondering lately because I've seen a lot people get irritated and think I'm just asking a stupid question with an obvious answer and it's making me wonder if I've been using rhetorical questions wrong.
