I'm curious about church rigamarole/traditions in mormonism regarding 50-year wedding anniversaries ... if any.
Heck, I can't really say that I know much about the non-mormon world, in terms of what moderate to affluent White folk, and their offspring, do when the couple hit the big 5-0...
Never will hit a big 50 for me, however, overall it depends on the person(s).
My wife and I both for the past two or three years have forgotten our anniversary. We do not worry about traditions or dates, since they are not relevant to being happy in a relationship.
