Although the one non-banal part of their conversation was kind of amusing - a critique of their parents various password options. They came to the topic via someone having had their cell phone stolen (or lost) for the fifth time or so, with a little side detour into identity theft. Which was really little more than self-fulfilling prophecy, considering they divulged the means to that theft at the tops of their lungs not two minutes later. If I'd known any more about them - any of the minutia ones peers collect over the school year, but especially the kind of things teachers know - I'd be well set up for a fairly remunerative crime spree.
It was a beautiful object lesson in both why they tell people not to use family names/birth-dates as password material and why universities come up with those lists of age-based cultural differences every fall. Sometimes I think the main difference between my age cohort and that of my parents/most people's grandparents is people my age and younger expect things to change and be fairly constantly fluid, rather than tacitly waiting for things to settle down and go back to normal (or perhaps "normal").
