I sent around 45 holiday letters and received about the same number of cards and letters from individuals. (We also receive quite a few from non-profits and businesses.) This is down from 150 plus going both directions in some years.
We got two Thanksgiving cards, two or three new year greetings, I think. Many cards were personal creations with pictures of families and pets. Letters recounted the COVID year. Some were just commercial cards with poinsettias, trees, stars, wise men, doves, wreaths, presents, Santas, snow, puppies, kittens, reindeer, snowmen. There was a glittery unicorn and two (2) with glittery Thomas Kinkade painting images. (The painter of light and glitter? Um.) There were personal notes here and there, many involving hopes for meet-ups "after."
Except for one cool reindeer card, the rest are consigned to trash (photos and glitter) or recycling. I save some nice ones in the Christmas decoration box to display in the future. I'll pack up the rest of the decorations soon and the holidays will be officially over giving way to tax season.
