Imagine a scenario in which you had to miss class. Now, divide a piece of paper in half. On one half of the page, construct a short message to a friend, explaining why you missed class and asking about the information you missed. On the second half of the page, construct a short message to an instructor, explaining why you missed class and asking about the information you missed. Each message you constructed had a similar purpose, but each had a different audience. How did the audience affect the message? In particular, how did it affect the Communication channel? Tone? Language? Content? . . .
