The most common complaint about cellphones is that people talk on them to the annoyance of people around them. But more damaging may be the cellphone’s interruption of our thoughts.

We have already entered a golden age of little white lies about our cellphones, and this is in generally a healthy, protective development. “I didn’t hear it ring” or “I didn’t realize my phone had shut off” are among the lies we tell to give ourselves space where we’re beyond reach.

The concept of being unreachable is not new – we have “Do Not Disturb” signs on the doors of hotel rooms. So why must we feel guilty when it comes to cellphones? Why must we apologize if we decide to shut off the phone for a while?

The problem is that we come from a long-established tradition of difficulty with distance communication. Until the recent mass use of cellphones, it was easy to communicate with someone next to us or a few feet away, but difficult with someone across town, the country or the globe. We came to take it for granted.

But cellphones make long-distance communication common, and endanger our time by ourselves. Now time alone, or a conversation with someone next to us which cannot be interrupted by a phone, is something to be cherished. Even cellphone devotees, myself usually included, can’t help at times wanting to throw their phones away, or curse this invention.

But we don’t and won’t, and there really is no need. That we have the right to take back our private time is a general social recognition.

In other words, we don’t have to pay too much attention to the rings of our own phones. Given the ease of making and receiving cellphone calls, if we don’t talk to the caller right now, we surely will shortly later.

A cellphone call deserves no more importance than a word from the person next to us. Though the call on my cellphone may be the one-in-a-million from Steven Spielberg–who has finally read my novel and wants to make it his next movie. But most likely it is not, and I’m better off, thinking about the idea I just had for a new story, or the slice of pizza I’ll eat for lunch.
