My dad acts as though he doesn't know very much at all, then spews out tons of information (about people or life in general) as though he had been waiting to tell the world for ten centuries. He pretends to be the nicest guy you'd ever meet, when in reality he's a highly competitive individual who used to get into dozens of fights. In short, he's been changed by his marriage to my mother but maintains a lot of the 'dark side' he used to have when he was a child, as proven by the weapons he keeps in his garage.
My mother has, and always has been, a bit of a nerd. She was quiet, shy, and very bad at making in-class presentations. As a result, my father was perhaps the biggest catch she would ever have a shot at. He saw her for what she was worth, and she saw him (probably) as someone who needed help. Hm? Conclusion: they worked nicely together, at least for a solid twelve years.
My brother is a lot like my dad in that he has his 'shadowy side.' He knows he can be a bit of a douche, and he almost loves the fact that people think he's a total jerk. He's intelligent and has a lot of fluid and concrete knowledge, thinks competitively, but also works under the influence of myself. He has always had an equally competitive older brother; someone who he admires but simultaneously wishes wasn't so good at what he does (oops, beginning to sound narcissistic). Conclusion: a bit of a jerk, but has the potential to be one of the nicest people ever to walk the face of the earth.
