In the last few weeks I've been entertaning myself trying to come up with a way to avoid answering some types of questions without being too obvious about it. I wasn't much successful, but maybe some of you can beat the challenge. Here's an example: You're talking to a friend and see someone looking your way. Your friend asks you: "Do you know this guy?" Now, for some reason you don't want to admit that you do. You don't want to say no either, because that would be a lie. If you avoid answering, it's like saying "yes, but I don't want to admit it". What would you say? My idea was to confuse things even more by saying: "Do I have to answer? Haha, but that's making you think I do know him, right?" Would you get fooled? What would you say instead? If you feel like expanding the situation into more than one line of dialogue, that's fine.
