Thanksgiving eve (last night), I met my friends from high school. During the three years of high school, we were all living in a dorm. We've all grown a bit since then, but after our little reunion I wondered what kind of indicators are there to predict where we will be--a topic we discussed while we ate our dinner. Would we be in Korea? America? Or some other place? Whether we can stay in America is pretty unpredictable, and so is the probability that my friends will be on the same continent as I am.
