Tumblr user mousemilf shares an endearing story of a holiday invented by her father. She grew up celebrating "Big Sandwich Night" -- a day when the entire family made a huge sandwich and ate it together:
I can see how this event could become popular. We need community, especially in-person community.
For a few years, my daughters and I celebrated Derpy Day, which is a brony holiday in which people bake muffins together in honor of Derpy, a minor character on My Little Pony: Friendship Is Magic. The girls eventually figured out that no one else at their school celebrated this particular holiday.
Does your family celebrate any unique holidays?
