I must be living in a cocoon. We have two teenage sons, both of whom text. I’ve never heard them or their friends talk in ‘text’. They write it, which saves them keystrokes, but they don’t say it.
Exactly, we expect our grandchildren to speak properly, they're not allowed to sit there and text while visiting, they are to DO things and visit, to MAKE things with their hands instead of mindless texting and computer nonsense.
I have a shop and my wife gets them sewing things for their parents on special occasions, it has worked out well and has been fun.
Same here with my two daughters. They use it when texting, but not in emails or most of their FB posts. They certainly don’t use it when speaking. I use it sparingly when texting to save time, i.e. u = you, etc.
