Around the time I began starving, in the early eighties, the visual image had begun to supplant text as culture's primary mode of communication, a radical change because images work so differently than words: They're immediate, they hit you at levels way beneath intellect, they come fast and furious.

Fall in love with a dog, and in many ways you enter a new orbit, a universe that features not just new colors but new rituals, new rules, a new way of experiencing attachment.

On the broad spectrum of solitude, I lean toward the extreme end: I work alone, as well as live alone, so I can pass an entire day without uttering so much as a hello to another human being. Sometimes a day's conversation consists of only five words, uttered at the local Starbucks: 'Large coffee with milk, please.'

The kinds of roles dogs fill can be hard to come by in human relationships. We touch the dog or the pet at whim. There is a lack of self-consciousness and a fluidity to it that is absent from most human relationships. If someone acted that way to you, you'd feel claustrophobic pretty quickly. It's a boundary violation.
