The semicolon is my favorite; it really is.
I don’t remember when I first learned about semicolons, nor do I have a mental list of remarkable semicolons in literature. I don’t want to have to treasure them, though the typical advice for writers of all levels is to use them sparingly, as if there’s a limited supply. This only breeds fear, which in turn breeds stigma: Semicolons are ugly, pretentious and unnecessary; they immaturely try to have it both ways. There are so many things to fear in life, but punctuation is not one of them. That semicolons, unlike most other punctuation marks, are fully optional and relatively unusual lends them power; when you use one, you are doing something purposefully, by choice, at a time when motivations are vague and intentions often denied. And there are very few opportunities in life to have it both ways; semicolons are the rare instance in which you can; there is absolutely no downside.
