Years ago a school-at-home family visited us from another state for a few days. Holly and one of the visiting girls brought a "preschool workbook" to me (a coloring book with puzzle pages) and asked what the directions said. It said circle in red... something. I don't remember the puzzle involved. But she asked if she had to use red, and I said no, to use any color she wanted to, and that she didn't even have to circle them.
The other mom stiffened, and when the little girls were gone said, "We believe it's important for our girls to follow directions."
That coloring book had no authority, and there was no advantage to anyone of that page being done according to arbitrary directions.
Some directions are more important than others. Some involve safety and property. Games have directions. Kits have directions. Recipes are directions. People can decide whether to play differently, put the kit together in a creative way, or tweak a recipe in progress.
It's good to make a conscious decision about what kind of directions you will follow without question, and which are less binding on you and your family.
