Kids these days have smartphones, and they only speak in text language, as we understand it.

"Soz", "l8rz", "bbz", these are the only things they say when they speak, if they speak at all, normally opting instead to simply Whatsapp you a disapproving message telling you something that involves a cat's face and some smiling poo.
