Dark Blue. Restrictions that I'm referring to are those I want to see placed on all teachers. Come dressed professionally for teaching. Teach only the specified topic of the class. If it's English, only teach English grammar. If it's History, only teach U.S. or World History. Et cetera. Keep your personal life's preferences out of your class. You have to remember that those students are there to learn spelling, reading, writing, grammar, arithmetic, mathematics, history, sciences, and for the higher K-12 grades, the shops (wood, electrical, metal, auto mechanics, et cetera).
Sex education should be optional for the parents to decide and not a mandatory class. Remember....they are NOT your children, only your students. They ARE the parents children.
Children pretend to be lots of things when very young, so don't play into it by straying from the curriculum and going along with their fantasies. Just teach what is required.
