What is Jonas’s reaction to rule 8?

In chapter 9, Jonas begins to read the rules that he must follow since he has been chosen to be the Receiver. Rule 8 states, "You may lie." At first, Jonas doesn't want to think about this rule. When he does reflect upon it, he realizes that he has trained since childhood not to tell a lie. Jonas recalls that the "reason for precision of language was to ensure that unintentional lies were never uttered." He begins to question whether all adults are allowed to tell lies. If he questions an adult to see if this is so, he will not know if the answer he receives is truthful.
Jonas lies to his parents for the first time in chapter 16. His mother explains to Jonas that to use the word "love" is inappropriate. When she asks if he understands why, he lies and tells her he does.
