You're an expert on classical literature who's been asked to join a panel on why 19th century women authors are relevant and influential to 21st century readers. Your premise is that these women of another age wrote about heroines who would fit quite naturally into our modern era with perhaps just a change of clothes and a chance to go to law school. You've prepared carefully, your bullet points are all in a row, and you've even planned ahead for any objections to your conclusions. All systems are go.
You're the next to last speaker, so you listen carefully to what the other panellists have to say. To your horror, one of the speakers ahead of you has chosen a similar point of view, even used the same examples, and said almost exactly what you were going to say! What are you going to do? You have just a few minutes to completely revamp your remarks so that you don't sound like a mimic, a trained parrot, or an unprepared copycat riding the coattails of the speaker who came before.
