    How to Answer an Unanswerable Question

    Every once in a while, you might just find yourself on the receiving end of one of these unanswerable prompts. Fortunately, we've put together some handy tips with three ways to handle yourself when you're put in this position.

    1. Embrace just how little you know.

    The worst thing you can do during any conversation is pretend that you know all the answers. Instead, it's important to be honest and admit that there are some things you just don't know. If you're worried about your pride getting in the way of that, just remember: You can't answer incorrectly if you don't answer at all.

    2. Ask why the question came up in the first place.

    You may not be able to provide concrete answers to difficult questions, but you can ask other, related questions to expand and deepen the conversation.

    3. Incorporate a little levity into your response.

    Life is heavy, so injecting some humor can't hurt. Of course, you don't want to minimize what anyone else in the conversation is saying—but you can redirect tough topics in a few silly statements. If it seems like people around you are appreciating the effort, then roll with it. If not, fall back and let the discussion continue on the same serious track.
