Harvard student may get some time off to think about concept of social boundaries

This:

When I was in college, we were told to always take note of strangers on our floor and if things didn't feel right, tell the RA or campus security. "Strange confused guy I've never seen before comes into my room and sits on my bed" seems like a damn good reason to call your RA or the cops. Our dorm room doors also locked automatically.

says it all...in a nutshell, Brett.

btw, I still remember an incident years ago, during my first year at graduate school, living in a dorm, and being cautioned by the dorm mother, or Residence Assistant. We were also advised to escort any guests we had over out of the dorm and to not let them wander around. There was an incident that same year (back in 1978), when one of the women in our dorm had a male guest over, and didn't bother to escort him to the front door of the dorm and out, the way people were supposed to do, under the dorm policy. The unescorted male guest wandered into the open-doored room of another young woman who was studying that evening, and this particular woman just missed being raped.....by a hair or two! Fortunately, through a cool demeanor and the use of her wits, the woman managed to get the troublesome, unescorted guest out of her room. An awfully close call, imho. Btw--have no idea whether the guy was intoxicated or not. My fellow dorm residents and I learned of this incident through the dorm mother.

Another grisly incident I recall that happened even before that occurred when I went to Northeastern for several months. I lived in a dormitory there, and again, one of the young women failed to observe safety policies for the dorm. The young woman had been sitting in the front lobby of the dorm during the wee hours of a Sunday morning.
A guy she'd never seen before wanted to get in, and the young woman, who was a dorm resident, naively let the guy in. Although nobody was molested or anything like that by this particular guy, the strange guy that the young woman had let in did a ton of damage and vandalism, including breaking one of the first-floor sinks.

All of the above having been said, I think that, in both instances, the dorm residents who'd broached the security of the dorm(s) were more than likely chastised strongly by the dorm mother(s), because, in either case, there were no other incidents like those.
