Laurie regarded his father coldly "I didn't learn nothing".
"Anything" I said. "Didn't learn anything"
"Look down" Laurie said. "Look at my thumb. Gee you're dumb" (and begins to laugh insanely)
"Charles was so good today the teacher gave him an apple"
"What?" I said, and my husband added wearily, "You mean Charles"?
This shows that kindergarten has already changed Laurie, possibly for the worst. This is the beginning. That preschool is going to be a bad influence.
"The PTA meeting is next week" I told my husband. "I'm going to find Charles mother"
"I'd like to know myself", I said.
"Ask her what happened to Charles" my husband said, "I'd like to know".
This shows that he is beginning to act out, unlike how he normally is. This adds to the conflict that kindergarten is changing him.
"She said it twice" Laurie said. "Charles told her to say it twice"
"What happened to Charles?"
This shows that "Charles" or Laurie had to be good to maybe avoid getting a call home, because normally when children act out and do it often they get a call home. He might not have wanted his parents to know that he is Charles. This shows motivation.
"Charles?" She said, "We don't have a Charles in kindergarten"
"Yes" I said, laughing, "you must have your hands full in that kindergarten with Charles"
This shows motivation on the mothers part, that she is so intrigued by Charles bad behavior to find his mother to ask her how she deals with it. To also maybe have a few words with the Kindergarten teacher.
This shows that Charles is getting worse, and his emphasis on twice seems to me like hes somewhat proud of what he did.
It revealed about the conflict that there isn't any Charles, and that we can infer the real kid that was acting out was Laurie. Which makes it clear that the reason Laurie seemed to take pride in sharing "Charles" bad acts is that it was actually him doing that. That the whole time he was confessing things he did.
