It all comes down to what they think of you. 

                    Chapters five and six 

Decorum: one of  the basic rhetoric principals. It states that depending on your audience, you need to act, dress and speak differently. Kate Middleton I believe is a clear example of a "virtuous woman" who uses decorum in her daily life. She, as many other conservative women: dress, speak and act differently depending on the occasion and event. In the chapters five and six, we can see how key points are highly repeated. These will enhance your abilities when using decorum in rhetoric. 

The first one is virtue: the audience needs to believe that you show your values. Kate Middleton embraces this key point by showing compassion to other human beings while doing activities like fundraisers and charity, which show her values and her "true self". Practical wisdom is also a key aspect, with this, you make your audience assume that you are wiser than you really are. This assumption is created by your body language, or in other words: by the way you act. Middleton, uses this skill, she appears to do the right thing on every occasion. Speaking quietly but contributing to the conversation, being and active listener and expressing herself clearly speaking in public are some of the examples. Finally: selfness and disinterest, make your audience perceive your attention, and make them think they are your "sole concern". If your combine these three skills along with decorum, it is pretty safe to assume that you have used rhetoric in a correct way toward your audience.
