The Rambam’s Fourth Principle: Commandments that refer to the mitzvos as a whole are not mitzvos

Mom and Dad are going out for the evening and they give their son instructions throughout the day. At 10:00 AM, they tell Junior, “No parties.” At noon, they say, “Don’t open the door for strangers.” At 4:00 PM, they say, “Lights out at midnight.” When they leave, they say, “Do everything we told you.” How many rules did Mom and Dad give Junior? Three: no parties, don’t open the door for strangers and lights out at midnight. “Do everything we told you” is not a separate agenda item.
