High Noon: Unsigned Xmas Cards

First, I should note that I never send Christmas cards. Mrs. O dutifully takes care of that holiday exchange of good will — and the cards that go with birthdays and other meaningful occasions throughout the year. However, I do read cards received — and have noticed a weird trend. I particularly enjoy getting cards that show photos of the sending family. I keep those. But Mrs. O & I have gotten two this year in which there’s nothing on the back. No holiday greeting. Not even the signatures of those out front. Which seems weird to me. If you go to all the trouble of sending a Christmas card, should you sign it. Izzit just me? (SR file photo)

Question: Is there anything about Christmas card exchanges that bug you? And/or: Do you like to receive Christmas letters that tell how the year has gone for sending family?
