Voice

Through voice we get a deeper understanding of who Ernesto is.
On page 41 he describes an experience at the hospital, "I made an impressive spectacle: gaunt, flushed, enormous eyes and a ridiculous beard whose shape didn't change much in all the months I wore it."Here he uses good syntax and sentence structure. He used this way to describe how he looked while at the hospital and I think it was very effective in getting across that same image in a little bit of a different way.
On page 47 Ernesto describes a meeting with some of Alberto's friends, " We shared big friendly hugs and wet immediately to celebrate by filling out guts with frothy liquid, as in the dignified practise on such occasions." Here Ernesto uses great diction or word choice to portray this image and I feel he picked powerful words to describe something that in essence is not that interesting of an event but he makes it seem as though it was fun and exciting.
