I've been thinking a lot about communication (I know--fun, right?!) and especially about questions. This is because asking and responding to questions (not just answering them) is a large part of communication.
So, 9(+) ways to respond when asked a question:
- Ignore the question. (& the person asking?)
- Refuse to answer.
- Admit that you don't know.
- Admit that you can't answer. (yet?)
- Use the fact that the asker has now stopped talking and take the opportunity to talk about what you want to.
- Pick a word from the question and talk about that. (Because not properly listening, or as a way to avoid answering the question directly.)
- Talk about a topic related to the question. (Because that's what you want to talk about, or as a way of avoiding the actual question.)
- Directly answer the question.
- Provide information/suggestions/ideas related to the question that will allow the asker to find (or decide) the answer themselves.
- Other?
I know the above is a generalization, and it won't apply to all questions but is a helpful summary of the options that are generally available.
Not all are always possible, appropriate, or useful, but all are worth considering before asking (or even answering) a question.
