I think some children are just naturally more 'compliant' than others. My daughter has a real sense of right and wrong and will, generally, veer towards the 'right' choce. She likes rules and hates chaos. She is neat and ordered in her thinking. She's like her dad so there's an element of nature in this one.
I suggest things sometimes and she looks at me askance and tells me it would be silly or dangerous or wrong! It's just her personality.
On the nurture front I am an oldfashioned mum in some ways. I think that children do need to respect others and they have to be taught how to do that. I think that children who are taught to share and be considerate towards their friends are more likely to be well liked in school. I think that teaching basic manners is imperative whilst the child is young and I do believe that children need clear boundaries. So perhaps this is a case of nature and nurture meeting in the middle.
I had a friend whose daughter was never told to say please, thank you or sorry when she was younger. The parents never interfered with playtimes, even if their child was snatching toys off others and making them cry. They believed that you have to let the child sort things out themselves, that it made them more independent.
Said child is now 12 and suffering horribly from a lack of friends. She still doesn't do please or thank yous. She doesn't understand the mechanics of playtimes or the rules of friendship. She is incredibly clever, but really lonely. How horrible must that be?
Obedience isn't the be-all and end-all of being a child, but it has to be an element in the repetoire. My dd is obedient on the whole and compliant. She also questions everything and refuses to go with the crowd just for the sake of it. At 11 she is becoming more rebellious with me, but at school, with other parents and when we're out and about she behaves beautifully. She does not, however, behave like a sheep and stands out from her wide group of friends for her individuality.
Obedience and sheepish behaviour are not necessarily twinned and the needs of society must come into the rearing of a child or you end up with the horror stories that often hit the MN pages about kids causing riots in cinemas and restaurants.
