The first day Dexter is at his new school, he punches a kid in the bathroom and hates pretty much everything about his new school.
Why do you think Dexter punched Robin? How would you act if you were a new kid at a new school?
When Ms. Abbott was talking to Robin on the playground, Robin lied to Ms. Abbott and said the fight never happened.
Why do you think Robin lied? Would you have told the teacher if you were Robin?
