So whenever someone picks up the phone and says, right off the bat, "Hi, John," I have a wierd moment of cognitive dissonance. My brain just can't grok that I should begin the phone conversation without identifying myself. So about half the time I end up identifying myself anyway, which sounds kind of silly, and the other half of the time there's an awkward pause while I mentally regroup. I imagine that kids growing up today will think nothing of being identified solely by caller ID. Personally, though, I long for a simpler time when phone calls still had an aura of mystery about them.
