Listening

ME: Hello, school group! Welcome to the Space Place's dome theater! We do just have a few things to go over before starting this movie!
KID: *waving his hand in the air* I HAVE A QUESTION! I HAVE A QUESTION!
ME: I will take questions at the end. Right, no food or drink, keep your feet off the seat in front of you, no cell phones, and I'm guessing some of you are wondering what those buttons on your armrests do.
OTHER KIDS: *nodding*
KID: I HAVE A QUESTION! I HAVE A--
ME: If you push those buttons at all during the movie, they will do ... nothing! We use those for live shows, where we ask science questions, and kids can vote in their answers. But hey--you don't have to take a test today! So yeah, you can push those buttons all you want. They won't do anything.
KID: I HAVE A QUESTION!
ME: All right, one last thing, and then I'll go start the movie. You might feel seasick in here, because it feels like you're moving when you're not. If that happens, all you have to do is close your eyes and that feeling should go away.
KID: I HAVE A--
ME: All right, I have time for a couple of questions. Yes, you seem to have one.
KID: WHAT ARE THESE BUTTONS FOR?
ME: I knew you were going to say that.
