3. when holden visits phoebe's school, he notices swear words
written and scratched on the walls. he suspects " bum"
has broken into the school and left the graffiti. what's a more likely
explanation about the identity of the person/people who wrote the
graffiti? (look at the museum's mummy scene for a clue.) how would
holden's realization of this change/alter his view of the world?
