I usually take on the job of writing all the Christmas cards - i have always done it traditionally as DH used to work in a job where he worked 7 days a week in December due to increased Christmas workload.
Over the years I have tried to reduce the list but DH is reluctant to cut people out. He has got rid of one or two but there are still 4 people on the list that I don't think we should send cards to as he no longer has any contact with them and in my opinion, he wouldn't even know if they've moved house as it possibly wouldn't occur to them to tell him. These are all people he worked with in his previous job - 10 years ago.
AIBU to insist that we no longer waste time and money in sending these people cards? DH says it is traditional and in any case one of the people we cut of the list last year then sent us a card. I pointed out that it was probably only because we have routinely sent them one in previous years. Some of these people have DCs whose names I have written down but they have probably grown up and left home by now.
I have told DH I am not writing cards for these people and if he really wants them to have a card he can do it himself - but I still begrudge the extra postage on top of the huge pile of family and real friends who we have to send cards to as they are spread out all over the country.
Incidentally I send 3 cards to people I used to work with but 2 of thise are very close friends and one of them I kept in touch with for a number of years and bumped into fairly recently so know she still lives in the same place and would welcome a card with an update on the family.
