Punctuation rules are simple and straightforward — right?
Imagine the following conversation between a Terrific Boss and a Hapless Employee.
TB: Why do you keep making so many punctuation errors? The rules are simple and straightforward.
HE: Really? Where can I find the basic rules for punctuation?
TB: Just Google "Wilbers punctuation."
HE: OK, I will, but how about if we talk about the rules for quotation marks? For example, do closing quotation marks go before or after commas and periods?
TB: In American English (unlike British English), commas and periods go before, not after, closing quotation marks.
HE: Got it. So when should I use single quotation marks?
