I recalled in the story, "Andado", that Laura did not tell her friends she was going to Don Andrés' fundo without her parents because they would think it improper. A chaperone was arranged as a security measure against inappropriate situations. As I read "Itinerary", it seemed to me this was a continuation of a Chilean custom. Girls and young women were chaperoned.
I read nothing else into it because I didn't have a positive picture in my mind of Laura's parents. (I assumed the narrator was Laura.) They didn't strike me as doing something to keep her safe, care for her, or nurture her. I based my opinion of them on the first story. Her father didn't even come to the airport to say good-bye, and her mother didn't acknowledge her when the plane returned to the gate for a delay. Parents who look after their daughter don't behave that way, in my opinion.
Each visit along the way reinforced how I felt about her parents. Maybe they thought providing their daughter with chaperones would reflect well on them or appease their guilt. It wasn't ever about their daughter.
I took my first flight alone when I was in the fifth grade. I flew to Chicago with my dad. He then put me on a plane to California. My aunt and uncle met me at the gate. We called my dad as soon as we could to let him know I had arrived safely.
On my second trip, I flew from Detroit to Miami and then on the Medellin, Colombia. There was no one to meet me in Miami. I had very specific instructions from my father on what to do. It never occurred to me that I would need a chaperone. Obviously, it didn't occur to my dad either! The only "danger" I faced was getting off the second flight in a city other than Medellin, wondering where in the heck my dad was, and trying to make a payphone call with quarters instead of pesos! That trip had a happy ending!
