Before the modern cell phone people simply did whatever it is they were doing without talking to someone on an electronic device about their largely insignificant lives. I have thought a good bit about why people text, or have to talk on the phone. In my opinion, and this is just my opinion, I think in the end we simply do not like or even want to consider the thought of being alone. With the acceptance and continued use of various devices, and behaviors that keep people "connected" the thought of not being connected, and the actual reality of not being connected makes many people uncomfortable. I think Blaise Pascal had us figured out when he commented on it in the 1600's
"All men's miseries derive from not being able to sit in a quiet room alone."
