Term for meeting more people near elevators?

So recently I’ve been dorming. I had to move from a rather isolated dorm near the hall end to a dorm next to the buildings elevator. Ive realized that since I’ve moved dorms, my new positioning has lead me to meet a lot of new people (in comparison to my old dorm.)

I’ve been told there’s a (psychological?) term for this. Not just elevators of course but public areas like bathrooms, water fountains, etc…

I guess my true question is what that term is, but for the sake of making it a decent fluther question just a general discussion about it. Have you experienced this? How had it affected you? I know I’m now much more social then I once was. Being forced to me social worked on me.
