Conversations with Normal People vs. MIT students

I’ve been observing a marked difference in the interactions I have with MIT students and normal people. It goes something like this:

Me: Hi, what’s your name?

Normal-person: I’m Annie, what’s yours?

Me: I’m Beracah, nice to meet you!  Are you a student or working?

Annie: <ensue 20 minute conversion & exchange informal contact info>

but on MIT:

Me: Hi!  What’s your name?

MIT-girl: <cold, withering stare, as though I’ve offended her><girl turns and walks away>

yep.  i love campus!
