We got booed for our boring wedding cake feeding. Just celebrated our 18th anniversary.
I told all of my three daughters this when I gave them very modest weddings. They may not have appreciated it at the time, but they do now.
As for that "stuff", my wife and I have a few orignal boxes in the garage which were seldom if ever used. More than a few of them have even been regifted to other weddings, bridal showers and the like.
My wife and I dug out our wedding video a few months ago, on our anniversary. I'd forgotten that we got some jeers at that moment, too - and by a lot of the older folks present! WTF?!
That video is a DVD dub from VHS - we were married in 1987. I've never understood the "custom" of smearing wedding cake on one's newly-minted spouse. A dot of icing on the nose is probably harmless, but some of the examples I've seen are as foreboding as the article suggests.
