Laurie describes Charles as how he wants to see himself.
When Laurie goes to kindergarten, he comes home every day talking about a bad boy named Charles who gets in all kinds of trouble. His parents are concerned, but decide that he might as well meet people like Charles now.
One day his mother asks him what Charles looks like and what his last name is. Laurie evades the last name question, but answers the first.
“He’s bigger than me,” Laurie said. “And he doesn’t have any rubbers and he doesn’t wear a jacket.”
Clothes are important to Laurie. They are a symbol of maturity, This is why he describes the clothes Charles wears and nothing else.
