Why do commas have so many rules? Does the period go before or after the quotation mark? How do I use an ellipsis? When is it appropriate to use a dash? What is an "en" dash anyway? Is a semicolon much different from a colon? Would it be better to use parentheses or a dash in this sentence? Are there gray areas where there really is no rule?
