What are the speakers talking about?

M: So, tell me, what’s the one thing that really makes you unhappy about modem technology?
W: I’m happy to get a chance to speak out. I know that a lot of people like the convenience of cell phones, but I find them truly irritating. People don’t seem to know when to leave them at home. I hate it when people use their cell phones in a restaurant or a store. It’s probably none Of my business, but it drives me crazy. One night in a movie theater, some cell phone began to ring and a guy behind me began to have a conversation right there during the movie. And the people who talk on the phone while they drive, well, they’re putting the rest of us in danger, aren’t they? There should be a law against it.
