* I bumped into a girl that I went to South Eugene High School with at the train station here in Padova, Italy. We were even on the same train. I was quite literally speechless for a moment or two.
* I worked with a person in San Francisco whose dad had known my dad and uncle in the same small town in Montana.
Utterly freaked out I contacted her via IM, not having actually known how to do that and not having spoken to her for a very long time and verified that it was indeed her ip address and she was indeed at that computer, but she had absolutely no idea how I had managed to ascertain that fact and was about as freaked out as I was by the episode.
We talked for many hours before it finally dawned on me exactly what had happened.
On the exact day that I had been checking firewall rules on my laptop with kernel packet logging enabled, at the exact second that I had accidentally alt tabbed to a terminal window that was tailing said packet log, she had done a search on napster for a song that I happened to have.
This is very much the weirdest coincidence I've ever experienced in my life thus far.
