Culture isn't all just about what can be tweaked and twitched in the simplest possible way. As people move around, they literally don't see what's around them, because they're wedded to earworms that are burrowing into their heads endlessly in a kind of negotiation with these tiny screens.

People are moving faster - you can see that in the streets. Partly that's because of the electronic devices, which encourage this.

An involuntary return to the point of departure is, without doubt, the most disturbing of all journeys.

Walking around becomes actually difficult. But the walking process is the oldest natural form of movement. It puts you literally in touch with the earth and the weather around you and allows you to get into conversation with people as you move, which seldom happens in the other ways we move.

As you withdraw energy from the city, you are also giving energy back. People are noticing you. You're doing something, you're there, the species around you absorb your presence into it, and you become part of this animate entity called the city.

The line of traffic advancing towards the rising sun looked like a procession of the returning dead. Every one of them, solitaries in clean shirts, smoking, checking mirrors to see if their reflections were still there, wore dark glasses.

I got interested in the contradiction between people who are understanding the city by not moving a single inch, by remaining in the same place all the time, and people like me who are constantly roaming around.
