Just about now it is 1/3 of a century since I first met my wife.
http://fbhjr.livejournal.com/773174.html 33 1/3 years since that party at Jack's place in July 1983...
In some ways it seems much less. In some ways it seems like she's been in my life from the beginning.
But, you could make a good case that meeting her was the start of my life. It certainly took it in a different direction.
Either way. 1/3 of a century is pretty good.
