I don't think he knows that!
Also, This weird idea that the "rich" schools don't have issues with partying is comical.
I have taught in rich schools, poor schools, private schools.
The rich/private schools party...hard. They have access to so much more along with parents that either "let them party at home" to be the cool parent OR that take vacations and leave their junior/senior kid(s) home alone for the weekend. With a lot of access to booze/beers and prescription meds.
The guys from Prep and Millard West in my frat partied the hardest and most.
