this is also cool

I found this here, but I'm not sure where it's originally from. I pasted the text in this blog to make it easier to read. And I changed a couple examples for clarity.

Punctating dialogue

• "This is a sentence."

• "This is a sentence with a dialogue tag at the end," she said.

• "This," he said, "is a sentence split by a dialogue tag."

• "This is a sentence," she said. "This is a new sentence. New sentences are capitalized."

• "This is a sentence followed by an action." He sat down. "They are separate sentences because he did not speak by sitting."

• She said, "Use a comma to introduce dialogue. The quote is capitalized when the dialogue tag is at the beginning."

• "Use a comma when a dialogue tag follows a quote," he said.
  "Unless there is a question mark?" she asked.
  "Or an exclamation point!" he answered. "The dialogue tag still remains uncapitalized because it's not truly the end of the sentence."

• “Periods and commas should be inside closing quotations."

• "Hey!" she shouted, "Sometimes exclamation points are inside quotations." However, if it's not dialogue exclamation points can also be "outside"!

• “Does this apply to question marks too?" he asked.
  If it's not dialogue, can question marks be "outside"? (Yes, they can.)

• “This applies to dashes too. Inside quotations dashes typically express–"
  "–Interruption" — but there are situations where dashes may be outside.

• “My teacher said, 'Use single quotation marks when quoting within dialogue."

• "Use paragraph breaks to indicate a new speaker," he said.
  "The readers will know it's someone else speaking."

• “If it's the same speaker but different paragraph, keep the closing quotation off.
  "This shows it's the same character continuing to speak."
