Please explain Penn as "social ivy"

<p>I don’t have a problem with what anyone else does who is not [family-wise] related to me. If someone wants to drink then its his or her choice, and I’m respectful of that, but if that person gets out of control at a gathering that I’m also at, then I’m out of there or at least getting as far away from that person as I can. </p>

<p>I realize that drinking is a big part of college culture, but there are great people who drink, so it doesn’t bother me, as long as I don’t do it. I’m quite accepting about these things.</p>
