At every few corners in major urban areas, you used to see phone booths.

Before cell phones, they served a significant purpose, of course, providing telephone access to the multitudes.

But now that theyve been disappearing, theyve taken more than dedicated phone lines with them.

Theyve removed a significant semi-private space, as well.

The old phone booth, while seldom perfectly quiet, facilitated several significant things:

(1) It was quiet enough so we could compose ourselves before conversations, thinking through what we were going to say.

(2) It did muffle some outside noises, making it easier for us to monitor our own voices, and hear ourselves think.

(3) It made it easier for listeners to concentrate on our messages.

(4) And perhaps most important, it kept our conversations confidential.

Ive never been comfortable talking business, surrounded by fellow passengers in an airport lounge, or when Im sitting in a restaurant. I dont want them to snoop, and I dont want to intrude into their acoustical space.

What we need to do, as I see it, is build cell phone booths.

They wont have a telephoneyoull bring yours. But there will be a platform for placing documents, and for four quarters, youll be able to buy five minutes of peace, at a shot.

My conversations are worth it.

Are yours?
