I truly have no clue as to what happened, and my gut does not say these kids are involved w/their friend's disapearance, but I do think they are trying to 'cover up' their own irresponsible behavior that night.
Even though it has been nearly 30 years since I was in college, there are alot of things that haven't changed. I lived in many diff apts and houses with fellow students during my college years, and even tho we had been cautioned and knew better, we were EXTREMELY irresponsible when partying, more interested in being with our friends, getting buzzed, flirting, etc than being concerned about our safety. We thought we were invincible-even if bad things happened to our peeps. We rarely locked doors, had no problem getting rides, partying with 'cute' boys we just met...
I am not now, nor have I ever been stupid or naive, but have certainly made stupid choices when drinking. Heck, even now (after reading WS for the last 5 years) I don't keep my house locked. I know, I know, that IS absolutely irresponsible- (and sometimes I think of neighbors finding me murdered and my pets feeding off of my undiscovered dead body after a few weeks because I live alone!) but my pals and I often laugh about how lucky we were that nothing bad ever happened to us because we were so irresponsible.
Not laughing about it now, because truly, there but for the grace of God...
