Communication Skills: the speaker and the audience

Public speaking involves two roles: the speaker and the audience. Using the following scenario, answer the question in a minimum of two paragraphs. You are presenting at a professional conference related to your degree. Twenty-two people are in attendance, and you have worked hard preparing your 45-minute talk. You notice that one of the attendees has a book in front of his face and appears to be reading, four others are texting, one is showing another the screen on her Smartphone, someone is eating from a chip bag, and two more in the front row are whispering to each other. As the speaker, what are you thinking and feeling because of the behavior of some audience members? Identify possible reasons for the audience's behavior. Should an audience pay attention to a speaker regardless of the speech and/or topic, or it is the speaker's responsibility to earn the audience's attention? Explain your reasoning.
