How to be obedient
Be respectful.
Part of being obedient is showing respect to your parents, honoring their ideas about what's best for you, and showing that you think they are worth listening to. Make sure that you listen when they talk and respond when they ask you to respond.
Don't ignore them in public. When you are out with your parents you might feel a bit embarrassed by them, but pretending that you don't know them or that you aren't with them is rude in the extreme.
