|It is VRP as a Persecutor to tell someone what "not to do" in an "I don't want you to," fashion.
A frequent inclination or reaction to such a statement is for the receiver of the message to actually do the behavior that is, "not wanted."
||The Green here is saying the behavior that the speaker Wants rather than what NOT to do.
Whether a speaker chooses to say, "I want," or "I would like," depends upon one's history with another person.
For example, with one child I may say, "I'd like you to wash the dishes," and he (or she) might consider the request as optional. So, for that child I would say, "I want you to wash the dishes."
