I am learning to text! I can manage a limited range of syntax, though I'm still incapable of capitization or emoticons. As I am working on a primitive phone which doesn't give me a virtual Qwerty but makes me count keystrokes (and where I still need to turn off the predictive text EVERY GODDAMN TIME), I now understand the lure of "r u" instead of "are you."
But I will resist, I tell you. To my dying breath ... Except in emergencies ;-)
And I will always use the right "your."
