This is a great article I read today in my school newspaper (the Daily Princetonian). It's written by a freshman and it's about this awful trend on college campuses of people meeting each other and then slowly but surely, acknowledging each other less and less. Fantastic. Well done Chelsea!
PS: Reminds me of this article I read a while back about Columbia paying its students to say hi to one another. Click on the word "click" (either one) to have a look.
