While it could be sometimes construed as awkward (not for me, but so I'm told), I find that seeing people in person after 5, 10, or 15 years (which is why I have so much fun at reunions) gives you a chance to reflect on who you were, where you are, and have someone help remind you of things that influenced your path.
In this case, I had a chance to see Petras (with whom I worked at Fact Communications in Tokyo) and whom I hadn't seen in 17 years, Jim Weisser (who I saw 5 years ago, but knew from 17 years ago) and Brent (who was at Int'l University of Japan) with me.
I would encourage you...even if it's only for 20 minutes/coffee, next time you are traveling somewhere, make the effort and reconnect with a friend from a past life.
