Talking about game stuff in public where people can overhear what you're saying can be fraught with danger. Most people don't play out fictional stories and events and so have no reason to discuss them as though they were the characters, which means that when most people hear such things they don't immediately reach the correct conclusion that you're talking about fiction.

This can make you sound depraved or insane. The best defence is to point out that no, you're actually just a nerd. Although some people may actually prefer to be regarded as depraved or insane.
