Out of curiosity, I checked my cell bill to see how many text messages my 17-year-old son sends in a month. He averages 20 per day and, of those 20, almost all fit entirely into the subject line and many are one or two-word texts. For the teenagers that send enough texts to bring the average up to 80, I would bet that most of their messages are extremely short. Given that, I think I could text like a teenager (especially if I didn't have a full-time job where my cell phones stays where it should - unused in my purse).
