I love this article about the private language developed by couples over time. My spouse and I already have a wealth of inside jokes and references and figure that by the time we've been married 25 years, we'll be completely incomprehensible to others. Of course, with kids around, it only gets worse, as all their favorite books, zany mishaps, and malaprops become incorporated into family lore. Hopefully detangling the content from the insider hugging will become part of a future lesson in Knowing Your Audience, but it's possible we'll just become more and more eccentric . . .
