In Percy Jackson and the Olympians: The Lightning Thief, what are six character traits one can infer about Percy based on the conflicts?

Percy is incredibly loyal to those people he cares for, a trait that we observe when he, his mother, and Grover have their confrontation with the Minotaur. After the beast grabs his mother and she dissolves in his grasp, the Minotaur goes after Grover. Percy says, "The monster hunched over, snuffling my best friend, as if he were about to lift Grover up and make him dissolve too. I couldn't allow that." He is willing to risk his own personal safety to protect Grover.

This willingness of Percy's to put himself in danger to protect another person (or satyr) shows his bravery too. He purposely attracts the Minotaur's attention in order to protect Grover, calling to the monster, "'Hey, stupid!  Ground beef!'" When he calls attention to himself in order to save his friend, Percy shows how brave he is.

In addition, Percy has a good sense of humor. After he arrives at camp and learns who Chiron really is, the centaur gives him a tour. Percy says, "I was careful not to walk behind him. I'd done pooper-scooper patrol in the Macy's Thanksgiving Day Parade a few times, and, I'm sorry, I did not trust Chiron's back end the way I trusted his front." Kind of gross, but very funny.

Percy is also optimistic and tends to give people the benefit of the doubt. When he meets Luke, despite the "bitterness" he hears in Luke's voice, the fact that Luke seems a little disillusioned with the gods in general, and that he sort of insults Percy, Percy says, "I figured Luke didn't mean to call me a nobody. He just had a lot on his mind." Percy sees the best in people and is willing to excuse Luke's behavior.

This optimism also makes him fairly trusting of others. When he, Annabeth, and Grover are at "Aunty Em's" (Medusa's) restaurant, Annabeth grows suspicious pretty quickly, but Percy continues to trust that this old woman doesn't have any desire to hurt them. He "was irritated with Annabeth for being so bossy, so rude to an old lady who'd just fed us for free." Percy's willingness to trust others—as he later trusts Ares, to an extent—gets him into a series of scrapes that could have turned out much worse.

Finally, Percy is also very social. He enjoys being with others, and he rejoices when he begins to feel accepted. But when he is claimed by his father, he is moved to cabin three, on his own. He hates it. He says, "I was absolutely miserable. Just when I'd started to feel accepted [...] I'd been separated out as if I had some rare disease." Percy seems to thrive on being with others, which is unsurprising given his other qualities.
