I am ancient enough to remember all sorts of rules of grammar and punctuation that have gone by the wayside, it seems. Such as using a comma at the end of dialogue, before closing the quotation and appending attribution, a convention that is also mysteriously absent in the archive.
Even if our children aren't actually being taught any of these things, there are numerous websites where one can self educate. Google is our friend. Failing that, one can real a book, an actual published book that has been printed and sold. It will be a revelation to see punctuation properly applied.
