There's not any "traditional" gift designation for 19 years, but even if there had been, well, we probably wouldn't have followed that anyway. Rob briefly considered combining the 15 and 20 year gifts by getting me a crystal china-man, but didn't have much luck finding such a thing, at least not in our price range. $3500 for a lamp? Not gonna happen. Instead, he got me a little diorama of a day-of-the-dead skeleton bride and groom. And we were apparently in tune on the day of the day theme since I bought him a day of the day cookie cutter as well as a skull shot glass and some Lil' Devil Cinnamon Toothpicks. Not exactly traditional gifts, but very personal and I think that beats the hell out of diamonds and what-not other things that advertising says you ought to buy for your sweetie.
The anniversary card that Rob gave me pretty much says it all.
