Lazy. Usually just go to church and watch American football (if it's on) or just doing lazy stuff with my family. And my parents also have a tradition of having special dinners, whether it be buying something like steak and making that into a dinner or ordering takeout. And it's almost always dessert day.
Sometimes, I'll do homework or study for tests if it requires either a lot of my time or are just due/scheduled at the beginning of the week.
