Yeah, i think what they have all said fits about right, if you are softly spoken and confident in what you say, people will listen to you, and then adopt your mannerisms.
I dont know if the rest of the guys will agree with me on this one, but i think you could even use really light kino to connect with someone, and put them at ease. Nothing too much, but a touch on the shoulder when you tell her something important could help her feel more binded to you, and therefore more relaxed.
