I think we both knew that, in practice, there is no real risk in being kicked out of school for hitting up a party on Fridays so long as you act with some baseline level of responsibility. In my case it wasn't even a dry campus (and few people other than freshmen were in school housing anyway, so the parties were on private property), and nobody had cars (campus was in the city). In this specific case, her judgement was based on mixing the legal and moral signals, but she does not normally buy into that.

I would describe her position at the time as slightly hypocritical, or at least poorly considered. To be clear, I don't think anti-kids-these-days-drinking attitudes are categorically extremely hypocritical, just often so.
