Per Schulz von Thun - The Factual Level contains statements which are matter of fact like data and facts, which are part of the message. - In the self-revealing or self-disclosure the speaker - deliberately or unintentionally - reveals something about him or herself, their motives, values, emotions etc. - In the relationship-layer the speaker expresses, how the sender gets along with the receiver and what they think of each other. - The wish or want contains the plea or desire, the advice, instruction and possibly the effects which the speaker is seeking.
