George Lucas says that Jedi children are exceptional. They are selected on that pesky midichlorian count and taken from their parents to be raised in a very controlled environment.
I'll tell ya what. Lets take a look outside of the United States and its young that are reared on pop culture and MTV and parents that want to be buddies with their kids. Take a look at the children that are raised in environments like the Jedi order is supposed to represent, like the Shaolin monastery, or Japanese educational system, or even here in the states in the Amish areas. Those strict environments help keep kids in line as much as parenting. Qui Gon tells Anakin, training to be a Jedi will not be a easy challenge. And if you succeed, it will be a hard life.
She is introduced to her new 'master' and is insolent to both Anakin and Obi Wan, who is a member of the council. I sincerely doubt any teenager would be so flippant with one of the 12 most powerful people in their world.
We are used to seeing obnoxious children and seeing sitcoms where the father is portrayed as a bumbling **** and the kids are the ones with all the answers. We have let our society become one where children are allowed to speak to adults as equals and this show reinforces that behavior.
Ask Josh, who has to teach kids everyday, if he wishes their parents disciplined their kids a little more, so they have an understanding of boundaries and following instruction. Ask him how often parents expect him to do their job of parenting and all they have to do is make sure the kid gets to the building.
