If they're not from America it's preferably like any other day.
However I was picturing a BDSM couple with a few kids and how they spend their normal daily lives. Maybe the wife is submissive in the father is the head of the household
What would 4th of July weekend be like for them?
Mundane and vanilla for some of it probably.
I could picture shooting off some bottle rocket sticking them up the wife's ass and firing them out side
It would make a great short story.
