The 'big rocks short story' doesn't feature highly - developed, named characters in the way a story with a complex plot would. The main character is essentially an everyman or everywoman figure. This figure is the one who has to deal with the task of fitting big rocks (symbolizing important life aspects) into a container. It's about the average person who is being taught the lesson of prioritizing important things over the less important, so the main character is more of a representative of all of us in the context of learning about priorities.
I don't know for sure as I haven't read the novel. But typically, there could be a protagonist who is directly involved with the 'cry' in some way. Maybe a young person who is brave enough to make that cry heard or a person who is on a quest to understand the significance of the cry.
