I also think that each character had their own style. Each freak had a different personality and trait as did the geeks.
Sam - a wimpy, mama's boy with parents who loved each other
Neil - Jewish, better dresser, with a father who was cheating on his wife
Bill - ultra nerd, goofy, son of a single parent
Lindsey - tough yet smart, pretty and still discovering who she is
Kim - a b***h who hates school and authority, her mom is also a b***h who has no respect for anyone
Daniel - a car loving, school hating punk, likes having fun, his parents are bums.
Nick - a major pot head, loves music/playing drums, father is a hard assed military man...mom is mentioned once.
Ken - wise assed, clings on to people, has a big mouth...nothing known about his family.
