Just to greycats...
do you actually know anyone from knox well enough to make that presumption? sure, there are those 'rich arrogant pricks' and sure, some may dominate the school. they may be spendthrifts and not have the best education. however, it's sort of unreasonable to assume that everyone who goes there (and any private school for that matter) is like that. because - surprise, surprise - you can't put everything under an umbrella like that, especially if you don't know people.
i hope i don't sound uptight etc but seriously, that kind of assumption is so elementary public school vs. private school.
