If I were guessing, I would say it's probably their 10 year anniversary, so let's just say they have some
"stick-to-itiveness," but they haven't demonstrated tons of it just yet. All the same, we'll send a nice chatty card wishing them the best.
BTW: They love to travel, so DH seems to think that this is just an excuse to go on another honeymoon!
He could be right! If one needs an excuse, any ol' one will do!
