Percy Jackson feels miserable once he gets his own cabin because it makes him feel lonely and isolated from the other kids at camp. When Percy first arrives at camp, he is assigned to cabin eleven. Although initially he feels that it is crowded and wonders why the campers cannot spread out to the many empty cabins that he sees around the campgrounds, he feels a certain camaraderie with the kids in cabin eleven. He is new to camp, but he is not alone because he has so many bunk mates.

They are together when they go to the dining hall to eat, sharing a table and telling one another stories. Then, after Percy is moved to cabin three, he occupies the cabin by himself. Despite some earlier grumbling about how overcrowded cabin eleven was, Percy is unhappy with being alone. He notes, “I don’t have to share with anybody. I had plenty of room for all of my stuff.”

Yet, he “was absolutely miserable." In the short time since his arrival, Percy had come to enjoy the friendship of the other campers in intimate quarters at cabin eleven. After all, Percy is someone who has never felt that he was like the other kids at school. This is because he was not like them. Although he never knew it before, he is a half-blood, which sets him apart from his classmates back home.

At camp, however, all the other campers are also half-bloods, so Percy finally believes that he fits in much more than he ever did. He was starting to feel at home in cabin eleven, and then very peremptorily, he is moved to his own cabin because it is clear that he is the son of one of the most powerful Greek gods, Poseidon. Moreover, the kids from cabin eleven seem to avoid him after his move to cabin three, probably because they fear him, and they also fear the possible danger that he might attract.
