David has a fit body, is slightly taller than his (younger) sister, and has a minimal amount of chest hair. Age:
David has a kind personality, but can also be a very stubborn. In general he's empathic and caring, but also shy and introvert. He has two good friends, but most of the time he prefers to be alone. He gets along well with most people, but generally he isn't very noticed and stays on the background. He has trouble expressing his emotions.
Most of his social handicaps are due to the fact that he's a highly functioning autistic, meaning that he's above average intelligent, but lacks the social understanding that normal people have. His handicap doesn't bother him and when he's with close friends or family he acts like everybody else does.
At high school he finds subjects easy, and most of the time classes are boring for him since the subjects don't challenge him enough. As a result, he's easily distracted and spends a lot of time daydreaming and living in his fantasy worlds. He's very creative and has a rich imagination. His fantasy world often blends in with reality, making him sometimes see/hear/feel/smell things which aren't there, or making him see things differently than other people see them. For example, he can view a person on the street and know for sure that this person comes from either the past or the future, due to the way they're dressed and act. He has his own code not to interact with these people and in turn is never approached by them either. He's used to seeing these kind of things and treats these imaginations as a normal part of life.
He values structure in his life greatly, and has trouble adapting to new environments/ dealing with new situations. He has a set system to do things and it's difficult for him to deviate from his usual rhythm. Due to his desire for structure, he follows his parents' rules to the letter and takes what's said literal, even when it's meant figurative. It's also hard for him to connect to new people, and generally he only maintains superficial relations with others outside his small circle. Relationship with family:
He was born and raised in a small family, consisting of his father, mother and one year younger sister. As a child he was a quiet boy, who preferred reading, puzzling, drawing, or playing with his toys, over playing with other neighborhood children. He gets along well with his younger sister and never minded playing with her, treating her as a good friend.
As he grew up, his sometimes awkward behavior became more noticeable, and eventually tests revealed that he's a high functioning autistic. Initially David had trouble to accept this, but within two years he grew comfortable with these test results and concluded that it didn't set him that much apart from others after all. If anything, David doesn't really fall under any of the typical cliques at high school. He isn't a jock, he isn't a nerd, he isn't popular, but he isn't bullied either. He can connect well with his classmates, but that's about it. Apart from one classmate, who is one of his two good friends, he doesn't have friends or foes in his class. He is virgin and he never had a girlfriend. He keeps his handicap to himself and only his family is aware of it.
