The giver Chapter 9 Why do the rules exsit

The rules exist to keep Jonas seperate from the community. Jonas is no longer part of it in the way he used to be. Jonas mulls over his peculiar instructions, realizing that he will no longer have much time for having fun with friends. He decides that he probably will not choose to be rude, since that goes against everything he has been taught, and he is not upset about being exempt from dream telling since he rarely has or remembers dreams to tell. He wonders what kind of pain he will have to face in his training without any medication. He then considers the final rule, which goes against all that he has been taught about language precision and the avoidance of exaggeration, such as using the word "starving" rather than "hungry." He wonders if all adults are allowed to lie, but he cannot confirm what the others have been told.
