No matter what you do, you will be under the authority of some kind. You should obey your parents, because, for the rest of your life, every authority in your life will be like your parents. They have blind spots, sins, and even inexperience. They will demand that you do what you might not want to do. They will push you out of your comfort zone. They will disappoint you. Even though they shouldn't, they may speak harshly to you. They might make mistakes.
