Who is Percy Jackson? What type of person is he in the first chapter?

In the first chapter, Percy Jackson was struggling to control his emotions, causing endless troubles, and always dealing with others. Nancy bobofit is annoying him on the bus. Many times, and still non-stopped. It seems like it’s very hard for him to calm down, his anger will only grow. Percy Jackson said: “I’m going to kill her” this shows that Percy Jackson is not really good at controlling his emotions. He used extreme words like -kill-. He is impatient. When Percy Jackson wants to fight back, Grover stopped him: “You’re already on Probation!”.  From Grover’s words, I can tell Percy Jackson might be a troubled-child. The principal is not satisfied with his behaviors, and Percy Jackson gets detentions from the school. Also showing he has been a troubled kid for a long time, because Grover said: “You know who’ll get blamed if anything happens.”. Grover is already used to staying with him. When Nancy bobofit snickered something about the naked guy on the museum stele, Percy Jackson turned around and said: “Will you shut up?”. This sentence showed Percy Jackson is straight-forward, he tell his thoughts aloud. Also, from the sentence: It came out louder than I meant to. I think he needs to be mindful of saying more respectful words. The principal often says to him: “Count to ten, get control of your temper.”. From his words and actions, it’s clear to see that he is someone who struggles a lot to control his inside, not just his feelings, also including his behaviors and actions. He is restless, causing trouble. Overall, he is not capable/able to keep and control his anger, that leads to all the trouble(the root/cause of the trouble).
