People make errors, most often out of ignorance. Trust depends on honest communication.

Errors are forgivable, manipulation or coercion are indefensible. Trust is a precious gift that once violated is hard to restore. They are halves of a whole, yin and yang. Neither can function as dominant or submissive without the other. Before a submissive can wisely transfer power, they must impower themselves.
