Why does Laurie misbehave, and what does he try to do by misbehaving?

Really
Laurie misbehaves for attention.  If you look at 's behavior at school, it closely mirrors that
of Laurie's behavior at home.  At school he hits children, kicks the teacher, does not follow
directions.  At home he spills his baby sister's milk, he calls his pop a dust mop, he talks
back.  What is amazing is that his parents are appalled by Charles's behavior at school yet seem
pretty oblivious to Laurie's bad behavior at home.  Ironically, they are worried that Charles
may be a bad influence on their son.  Thatis revealed at the end of the story when the mom is
informed by the teacher at the PTO meeting that there is no Charles in class.

Laurie is a kindergartner whose bad behavior at home has followed him to the
classroom.  He enjoys the attention.  He loves the attention he gets at school by misbehaving
and the joy the next "Charles story" gets at home.  The only time Laurie is really
sullen in the entire story is when Charles is being a good teacher's helper.  He is sad there
are no fun stories to share at home.  Needless to say, Charles's good behavior is short
lived.

I would love to know what happens when mom gets home from the meeting!
I am guessing dad will be surprised too!
