Definition for this thread: Uncommon is any card you send but never receive.
Could be those New Years and Winters Solstace cards.
Arbor day?
Flag Day?
President Ford’s birthday?
My daughter sends cards on Earth day and also the town’s Founders Day postcards the local booster club gives out at the street fair each year. Never gets any in return.
My brother-in-law sends reverse-birthday cards. He says he can’t be organized enough to send everyone in the family birthday cards on their birthdays, so he sends them all on his own birthday.
I go to those e-card sites and send stuff just on the odder holidays. Hugging day, League of Nations day… And they have some of the funniest jokes for those.
And I’m planning to send some for National Shelter Dog Month.
One year, after I sent no Christmas cards, I sent a few Groundhog Day cards. I made them on Print Shop. I used the program’s image of a tyrannosaur, and added the caption, “Eek! A groundhog!” Inside, it wished the reader a happy Groundhog Day.
