I just saw a statistic (here) that teenage girls in the USA send an average of 135 text messages every day. I find that number mind-boggling.
Even though I am an old fogey, mostly out of touch with such new-fangled things as texting, I do know how to do it. In fact, I probably send at least one message a week! Sometimes even two.
Do my students in Brunei on average send as many as 135 messages a day? Maybe they send even more. A couple of days ago, I told my MA student that I only use my mobile phone two or three times a week, and her draw dropped in stunned incredulity. I guess there's a generation difference here. (Or maybe it's just that I'm a bit of a loner with not too many friends!)
