So, according to my 12-year-old it's, like, totally unnecessary when I sign off texts with my name. OK?
"The other person knows who the text is from, Mum. Your name comes up right above it." Cue eye roll from said 12-year-old here.
And that's true, of course, but I don't know, I still like to end my messages with my name; my initial at the very least. Call me old school, I'll take that. And I'm not going to stop doing it, styg (that's text speak for 'so there you go')...well, actually no it isn't, I just made that up.
If you ask me this new-ish language of text messaging is three parts depressing (it represents the fri#*ing demise of the written word!) and one part entertaining (decoding can be a little bit fun).
