In J.D. Robb's "Portrait in Death," a discussion takes place about the common saying that implies those who cannot succeed at a task often end up teaching it instead. Roarke references this idea with a quote, suggesting a certain cynicism about the validity of such a statement.
However, Eve counters his viewpoint with a pointed question, emphasizing the contradiction in the notion of teaching without the practical ability to perform the task. Her response indicates a belief in the importance of experience and competence in teaching others effectively.
