As a member of the 18-30, twentysomething crew, I'm gonna go out on a limb here and throw some of my generation under the proverbial bus. MANY-not all!- kids born in the late 70s/80s have had overly involved parents who raised to be believe we "special" and "unique" etc. I really feel that, even among my friends, there is a sense of entitlement and selfishness that astounds me within my peer group. Kids demanding cars at 16....Friends who started working their first job at 23!...Volunteerism a non-existent idea...all about them attitude. Not everyone in my peer group is like this, thank goodness, but having gone to a large Southern university and coming from an upper middle class background, I can certainly understand and see where some of the stereotypes for these diasffected youth could come from.
Instead of worrying about friends safety, these girls were worried about getting home "on time", not getting caught drinking/doing drugs whatever. Putting their personal concerns over their friends to avoid trouble whatever...even though I bet these girls knew something fishy was going on as they waited for significant time by the vehicle at the arena.
Just some thoughts!
