I was annoyed at my cousin (14) who kept texting the entire time I was visiting - non-stop. knowing him to be a smart kid otherwise, I asked wasn't this going back in technology when you could call and convey the message in a few seconds? He seemed to agree but couldn't kick the habit.
That made me thinking, that when it comes to communication, we as men (or atleast the more introverted among us - language-usage-wise) always prefer lower and lower levels of intimacy while communicating with friends - texting is preferable to email is preferable to calling is preferable to meeting.. I wonder if a semaphore simulation on a cellphone would ever catch up!
