Oh yes definitely down this year. Whilst I like seeing the cards up, we both find writing and sending them an absolute chore. I think at one time when my husband was still working we'd have well over a hundred, on retirement it was around 70, now it's down to roughly between 50 and 60 which is the number we send out. My husband still gets cards from a handful of clients who he has maintained a relationship with, I could well imagine not getting such cards if he was no longer here.
I would also add that our adult children who have established their own households don't send cards, they never got into it, in spite of having a wide circle of friends, far wider than ours quite honestly. I think card sending will eventually die out, the younger generations don't communicate with each other in this way and keep up with acquaintances who they don't see for various reasons, in other ways, hence there is little need to reaffirm the relationship annually by way of a Christmas card.
