I don't mind the Christmas card round because, as Rosie said, it does keep one in touch with friends who live beyond normal visiting distance, even if the 'phone is utilised occasionally. The cards I dread are those whose sender includes some sort of resumé of the past year's doings. I have a relative (distant in both senses) who used to adopt such practice. I decided one Christmas to do the same but outstrip her in the number of pages of inconsequential 'news'. I wasn't sarcastic or rude but simply mirrored her format. We still exchange Christmas greetings but the junk mail has ceased. :-)
(Dujon) I get a few of these, some intended for my late mother. The senders know she has died so they are addressed to me. Well, what the hell, it's the same address. She used to say "Oh, poof, who wants to know all their comings and goings every minute of the day". For her, as an essentially sweet-natured person, that is the equivalent of Foul and Abusive Language, and I fully concur. The full horrors of these things are described here. Well worth a look. There's a book as well.
These people should start blogs. Then their outpourings can be ignored without effort. Come to think of it, I've seen a few blogs like that, words cast into the void with no visible sign that anyone, anywhere, is reading it.
I'm awfully glad that very few people know my address. That, and I keep moving house. It's also nice to not have the Christmas card question, as in France one sends cards at New Year, and so I have a marvellous excuse not to bother.
Sorry, but I like receiving them and send one to a selected few on our list. It's better than just a card, but not as good as a proper correspondance over the year(which I'm hopeless at).
