We are increasingly a no-nonsense society. We used to look at college students' irresponsible behavior and sort of shrug. We dismissed it as largely a rite of passage.
Maybe the economy gives us pause too. The economy has made multi-generation households more practical. Maybe young people can give more serious thought to "staying home" once high school is done. Not to be idle, mind you. The landscape is dotted with places where one can take classes. Stay close to home maybe. The Internet is an ever-growing vehicle for personal advancement that allows you to progress from anywhere.
An occasion to honor the school and its traditions was abused. Why? It has become an element of college student culture that it's quite fine to do so. This is the element that causes limits on off-campus housing. It's the element that persuades a restaurant owner he has to post a $1.50 minimum purchase sign.
