Why so many people called greenbriar as an "antisocial" place?

<p>I am just wonder that why so many people called Greenbriar as an “antisocial” place.
How it was antisocial? I am pretty curious about it…</p>

<p>Greenbriar is a converted apartment house consisting of studio and one bedroom apartments. It is not dormitory style. You have your own bathroom and kitchenette. So there is no need to “mingle” in a common lavatory, hallway or dining hall. You have to make the effort to get to know the other people in the building.</p>
