What are six text citations that foreshadow that Laurie is not telling the truth about Charles?

When Laurie comes home from school, shouting all the way up the hill, he tells his mother: “Charles yelled so in school they sent a boy in from first grade to tell the teacher she had to make Charles keep quiet." Laurie is, at this very moment, engaging in the behavior that he claims Charles was guilty of, which sounds a lot like a lie.
When Laurie's father asks what Charles looks like, Laurie tells him “He’s bigger than me, and he doesn’t have any rubbers and he doesn’t ever wear a jacket.” This description of the phantom Charles sounds like Laurie is describing what he wishes he was like: bigger and able to defy his parents by not dressing as they make him dress for the outdoors.
When Laurie has been excluded from the class exercise activities because of his behavior, he turns the situation around by making it seem that he didn't want to do the exercises, even though he has the ability, which he demonstrates to his father by touching his toes. Again, he casts Charles in this role that he is only demonstrating.
Laurie becomes emboldened after all the stories he tells about Charles's over-the-top behavior, and this is how he is able to get away with pulling a wagon full of mud through the family kitchen.
When the PTA meeting is drawing near, Laurie describes Charles's behavior as improving dramatically; it is really Laurie's behavior that is improving because he knows his mother and teacher will soon have a one-on-one conversation.
Because no one stands up in the PTA meeting to acknowledge and apologize for Charles's behavior, it becomes clear that it is Laurie's misbehavior and that his mother is in the dark about what her son has been up to.
