Why do you think there are differences in punctuation for salutations depending on whether the letter is professional or personal?

Discussion Topic 1: Do you use semicolons when writing? Why or why not? Do you think your habits will change now that you have studied this chapter? Explain.Discussion Topic 2: Lewis Thomas wrote about the semicolon in The Medusa and the Snail: The semicolon tells you that there is still some question about the preceding full sentence; something that needs to be added. The period tells you that that is that; if you didn’t get all the meaning you wanted or expected, anyway you got all the writer intended to parcel out and now you have to move along. But with the semicolon there you get a pleasant feeling of expectancy; there is more to come; read on; it will get clearer. Is this how the semicolon makes you feel when you see it in print? How do you think a semicolon differs from a comma or a period in the way it makes a reader feel?Discussion Topic 3: Search an online bookseller or your local bookshop to find an interesting book that uses a colon in its title. Share the title, author, and a brief summary of the book with your classmates. The summary should be in your own words.Discussion Topic 4: In this chapter you learned that business letter salutations (Dear Ms. Lawrence) are followed by colons (when using mixed punctuation), not commas. Commas are used in salutations in personal correspondence. Why do you think there are differences in punctuation for salutations depending on whether the letter is professional or personal? And why do you think punctuation after salutations is different for business letters and e-mail messages?Discussion Topic 5: On the fiftieth anniversary of the assassination of Dr. Martin Luther King, Jr., columnist Dick Evans wrote the following about him: “My clear recollection was being stunned by the power of his intellect, blown away by his extraordinary command of language, and its deployment as an instrument of social change. He spoke in perfect paragraphs; you could hear every semicolon.” What do you think he means by this? Share your interpretation of this quote with your classmates.
