I have a friend who firmly believes that everyone should make up their own holiday--complete with traditions--and celebrate it every year. Hers is summer solstice (and she was incredibly disappointed to learn that it is a national holiday in much of Scandinavia). For the past couple of years, she has thrown a summer solstice party, and the tradition is to stay up and watch the sun set on the longest day of the year.
Bryn always likes an "itinerary check" in the car. We had swim lessons last night, but there is nothing special planned for tonight. Instead, Bryn had a great brainstorm on our way to school.
She offered, "Is this a good idea, Mom? Tonight, we should go knock on doors and ring doorbells, and collect good food."
I'm not at all sure of the audience for her invented holiday tradition, but I like her thinking.
