This post by A Cup of Jo presents a wonderful way to teach children how to jump into a conversation without interrupting. When you start out studying language and discourse analysis, you often look to children--and pay attention to when they "disrupt"--to identify the "hidden" rules of conversation. Certainly, knowing when to jump in and take a turn at talk is a skill we are not born with. With time (and some nudges from mom and dad, etc.), we learn to listen for the context, the non verbals, etc., and eventually we get it. Most of the time in a conversation, only one person is talking. Thanks to A Cup of Jo for the great tip!
