Answer:
Christopher Boone is a fifteen-year-old boy with Asperger's syndrome, a form of autism that affects how he interacts with others. He is the main character and narrator of the novel, and he gives us a different way of seeing the world. He is also brave, smart, and strong in facing the problems he encounters. He changes a lot throughout the story as he finds out more about himself, his family, and his surroundings. He begins as a boy who follows strict rules and routines, who hates lies and strangers, and who is scared of many things. He also loves math and logic, and he wants to be an astronaut. When he investigates the death of his neighbor's dog, Wellington, he uncovers secrets that break his trust in his father and make him doubt his own identity. He decides to leave home and look for his mother, who he thought was dead, in London. On his journey, he meets many challenges and risks that push him to change and grow. He also meets new people who help him or hurt him. He finally finds his mother and learns to forgive his father. He also takes his A-level math exam and gets a high score and shows his skills. By the end of the novel, he is more confident, independent, and optimistic about his future.
I would say that Christopher's personality is curious, honest, logical, and loyal. He is curious because he likes to learn new things and solve mysteries. He is honest because he always tells the truth and hates lies. He is logical because he thinks in a clear and organized way. He is loyal because he loves his family and friends, especially his pet rat Toby. However, Christopher's personality also has some difficulties. He is sometimes rude, stubborn, and violent. He is rude because he does not understand other people's emotions or expressions. He is stubborn because he does not like to change his mind or habits. He is violent because he hits people when he feels threatened or angry.
I hope this helps you understand Christopher's character better
