&gt;You really don&#x27;t know that people use cellphones to keep in touch with friends?<p>&gt;Did you miss the last 10 years or something?<p>I guess I did miss the last 10 years then. I am old-fashioned in that regard.<p>I prefer friends who don&#x27;t require me to be available 24&#x2F;7 (unless it&#x27;s an emergency or something like that). I am happier to interact in &#x27;bursts&#x27;, that is, exchange thoughts in one intense session, or writing longer messages, rather than the trickling 1-message-per-hour that seems to be so fashionable today. I like to be either part of an interaction, or not. And not in a perpetual conversation that never stops. But hey, to each their own. I know that other people like me exist.
