You know what though...kids don't always knw how to properly behave, and we understand that. All of you who have told your stories also have done the one good thing to teach them proper behavior...you ahve taught them proper behavior!!! By telling your child you don't mock those less fortunate, or by telling your child he stole from a hungry child and now you will donate that puddding and more, you are teaching by exampe.
I have a SIL who, thank God, lives 1500 miles away. She has 2 children, and teaches them nothing other than they are God's gift to humanity, they should do whatever it takes to get their needs met. I shudder to think how these children will grow up. Any bad behavior is not corrected...she looks at us and says "well, he's 5" or "he's 6". Yes!!!!!!! We know they are young children and when young children behave badly they need to be told, taught, instructed, guided whatever you want to call it so they recognize that their behavior is not acceptable, and that is the parents job. Clearly, there are many parents in the world(my own SIL included) who don't have a clue how to parent. Sad for the future of their kids. I firmly believe that my 2 nephews will be very socially isolated in years to come, because they will behave badly, others will not want to spend time with them, and they will not understand why, since they have never been taught.
