What are two examples of Laurie's misbehaving at home?

In
"," most of Laurie's misbehavior at home is
disrespect and bad manners.  Since we only
see him interacting with his
parents, this is directed toward them.  There are several examples
in the
story.

The narrator, Laurie's mother, describes how he comes home
from
his first day of school,

...the
front door slamming open,
his cap on the floor, and the voice suddenly become
raucous shouting, 'Isn't anyone
here?' (1)

Slamming the door,
throwing his cap on the
floor, and disrespectfully shouting in the house are all clearly bad

behavior.

Additional instances of Laurie's bad manners and disrespect
occur
at the dinner table that night. His father asks him what he has learned
and,

Laurie regarded his father
coldly. 'I didn't learn nothing,' he said
(1).

We are told that he was speaking with his mouth full
during this
conversation, and then,

Laurie slid off
his
chair, took a cookie and left, while his father was still saying, 'See
here, young man'
(1).

So, Laurie is
disrespectful to his father, speaks
ungrammatically, probably deliberately,
speaks with his mouth full, does not seem to finish his
dinner but takes a
cookie, nevertheless, and leaves the table without asking to be excused,

while his father is still speaking to him.

These may all seem like
minor
infractions, but it is clear that the "sweetvoiced nursery-school tot"
(1) has come
home a very different child!
