Written in a somewhat poetic style where the sentences may be like this one: "But home, too, was hard to get an image of, harder still to think beyond the last curved enclosure of the desert, where it seemed I had left the better portion of myself as one among innumerable grains of sand, how in the end the weather-beaten stone is not one stone but only that which has been weathered, a result, an example of slow erosion on a thing by wind or waves that break against it, so that the else of anyone involved ends up deposited like silt spilling out into an estuary, or gathered at the bottom of a river in a city that is all you can remember."
The erosion "on" a thing and the "else" of anyone are quite characteristic.
