OMG this is obviiii
Percy loves to be in water, he can hold his breath underwater with little to no problems at all. He can read greek easily which he thought at first was a reading disability.
Percy has never been "normal" in his life. What the heck does "normal" mean anyway? Well, it probably doesn't refer to somebody who has attended six different schools in six years. That's right – Percy has knack for getting kicked out of school. It's not his fault, though. You see, trouble seems to find him wherever he goes. He's a trouble magnet, no matter how hard he tries to keep cool and make himself invisible. Take, for example, his school trip to the New York museum:
I was trying to listen to what [Mr. Brunner] had to say, because it was kind of interesting, but everybody around me was talking, and every time I told them to shut up, the other teacher chaperone, Mrs. Dodds, would give me the evil eye. (1.31)
Sheesh. He gets in trouble for trying to pay attention.
Percy is used to being the outsider, the loner, and the dummy. He describes himself as "a troubled kid" (1.9). The fact that he has attended six schools over the past six years tells us that he must be really good at adapting to new places, but that he probably doesn't have many friends. During his sixth-grade year, Percy attends Yancy Academy, a nice boarding school for students with learning disabilities. Most of his classmates come from families that do not need to scramble for money like Percy's family does. While his classmates talk about what fun adventures they have lined up for the summer break (like travelling to Switzerland, taking a cruise to the Caribbean, etc.), Percy doesn't tell them that he will spend his summer working various jobs and figuring out where he will be able to go to school in the fall. Later on, when presented with a free stay at a Vegas casino, Percy says,
I couldn't remember the last time I had so much fun. I came from a relatively poor family. Our idea of a splurge was eating out at Burger King and renting a video. (16.200)
Percy comes from a very humble background, allowing him to be grateful for simple pleasures in life.
Growing up, Percy never knew his dad. His mother (who we'll talk about in a minute) eventually married a seriously heinous dude name Gabe Ugliano, or Smelly Gabe. They live in an apartment in Queens, NY, and Gabe likes to make Percy's life and Percy's mom's life a living hell. As a result, Percy's life perspective can be a bit negative at times:
I could start at any point in my short and miserable life to prove it. (1.11)
See? When he begins telling us his story, he's a bit on the grumpy side, giving us the sense that he is angry at someone or something. He talks about the lies parents tell their children and counsels us to believe these lies:
Believe whatever lie your mom or dad told you about your birth, and try to lead a normal life. (1.2)
This bit of advice tells us that Percy distrusts adults, but that he also feels that staying ignorant of certain truth is way better than pursuing this truth. He's disgruntled.
As if life weren't rough enough, Percy is dyslexic and has attention deficit disorder. This makes learning in a mortal classroom a billion times harder for him. He describes what it's like not being able to focus well in the classroom:
I have moments like that a lot, when my brain falls asleep or something, and the next thing I know I've missed something, as if a puzzle piece fell out of the universe and left me staring at the blank place behind it. The school counselor told me this was part of the ADHD, my brain misinterpreting things. (1.106)
Studying for final exams is a complete nightmare for him. All the words in his textbooks go "swimming off the page, circling [his] head, the letters doing one-eighties as if they were riding skateboards" (2.18). Fortunately, his favorite teacher, Mr. Brunner is a really good teacher (Latin and Ancient Greek culture) and thinks that Percy is the bee's knees. He sets very high expectations for Percy, saying, "I expect only the best from you, Percy Jackson" (1.66). Mr. Brunner is the only teacher who really believes in Percy's abilities, and Percy tries hard to do well in his class.
