I just re-read all the comments on this thread and started having memories of my grandparents (my Dad's mom and dad). They celebrated their 50th anniversary in 1967 (I was 12 years old). At the time, I did not appreciate what was happening, or NOT happening either! I've had years to think about "family matters" and "family dynamics" now, things I understood better.
My grandparents had 8 kids, 6 boys and 2 girls. At their 50 anniversary, all 8 kids were married, working, and had families of their own. Some were better off than others, but everyone was happy with their own lifestyle. The brother's and sisters were somewhat dysfunctional, (or maybe it was just MY dad, I'm still not sure).
But anyway, the kids decided to go together and their parents a 50th year anniversary gift. They all pitched in. Each one contributed. When it was over, here's what they did. They put together a money board. It had 50 - one dollar bills glued to it with "Happy 50th Anniversary" spelled out with glued glitter, and a copper tea pot!
At the time, it seamed pretty impressive (as a 12 year old kid), but looking back now, I am think to myself ... what a bunch of cheap-o's! 50 years for their parents and they came up with this hair ball idea! You would think each kid could have given at least $50 each, and probably, there was still enough among us grand kids, if we collected our pennies, we could have bought the tea pot!
Oh well, as a kid, you just don't see things or understand things I suppose.
Hopefully, your 50th was SPECTACULAR! And your kids got you more than just a copper tea kettle! --- Congrats again!
