How does Larry McMurtry use imagery in Horseman, Pass By?

Imagery:

I could listen all night when Jesse got to going back over his life, but the story never lasted long enough, and it always ended with him getting tireder and more sad. (Chapter 1, p. 20)

For dessert that night Halmea made a big freezerful of peach ice cream, rich as Jersey milk and thick with himks of sweet, lockerplant Albertas. pg. 9
