I was just invited to the fiftieth anniversary of old neighbors of mine where they will celebrate their years of happiness by renewing their marraige vows. Does anyone else find doing so under these circumstances odd? I understand a couple renewing their vows after being separated or riding out an affair, but people do this to celebrate their marraige on auspiscious anniversary's more and more. Maybe it's just me, but I don't understand what part of "Till death do you part" implies an expiration date while you're still, you know, alive.
