What are three examples of Lauries poor behavior at home?

In
"," Laurie's mother anticipates some behavioral changes when her son starts
kindergarten, so she is not too surprised when Laurie is rude to his parents when he comes home
from school. Arriving home after his first day, he throws his things down and yells. The
rudeness appears irregularly, accompanied by bad jokes and insults at his parents'
expense.

In addition to making impolite remarks and demands, Laurie becomes
very self-centered. He dominates the conversation with endless stories from his day at school.
He is especially impressed by Charles's antics, his disrespect for the teacher and the other
students alike, and his outright violence.

The plot of the story hinges on
the biggest example of his bad behavior, lying, which for weeks goes completely unnoticed by his
parents. He has lied about everything Charles did: Charles does not exist.
