But, there's an unintended consequence.
Instead of hanging the card with all of our other Christmas cards as part of our holiday decor, the card is opened and then left on the counter for the family to see. And on the day after Thanksgiving, when I clear the house of autumnal clutter, I recycle the card. So, instead of having their photo and greeting occupy a vaunted space on our Christmas card wall for an entire month or more, the card is left on the counter for three days and then forgotten.
Keep those cards and letters coming folks. I love all kinds of friendly greetings. Just know that some will be kept longer than others.
