We get one from friends. The Dh is gorgeous, and gave up his job and hobbies to follow his highflying wife. All the round robins are about her. Last year's one started with 'As most of you know, [DW] won the world championships in [her hobby] and the year got better there on!'
The truth is, that he feels overlooked and resentful and she has a glittering career and he gave up everything for her as she has to fly all around the world, and she bosses him around and reminds him that everything they do and have is because of her and her success. So I always see beneath it and worry about them both a bit, because they are both trying to maintain this fantasy of a perfect life.
Which reminds me of that e-mail that recently went viral by the retired navy captain who e-mailed his children to say how disappointed he was in them. One bit he said was that all their friends talked in glowing terms about their children, and he couldn't. i wanted to say 'everyone presents their life in glowing terms in that scenario!! That is what you do! That is what a christmas round robin DOES!'.
They are always a triumph of wistfulness over reality.
