The expression Ignore it, and it will go away does not apply to being chased by a dozen cop cars… Trust me on this one.
Always capitalize the beginning of a new sentence, even one that follows an ellipsis. Use three dots in an ellipsis; five is right out. Always use some sort of punctuation at the end of a sentence.
When you’re referring to the words themselves, italicize them. When you want to give a word or words special emphasis, italicize them.
