During a Q&A period after, say, a screening or a lecture, is for just that: Questions and Answers.
Let’s review how this works, shall we?
The person in the audience asks a question, which, ideally, is followed with an answer from the speaker.
Notice nowhere did I say anything about the audience member making a stupid, self-aggrandizing speech.
I find myself at Q&A sessions frequently during my rich escapades around the cultural landscape of Los Angeles, and I don’t think I’ve ever managed to sit through one where there weren’t a couple jerks in the audience who raised their hands only to launch into fifteen minute stories about their completely unfascinating lives. This needs to stop.
Please help me spread the word. In this matter, as in so many others, tasers are quite helpful.
