Also, I doubt that you can act like a real alpha male when alone in your room. I suspect you can just think you are acting like one because your not seeing the nonverbal communication from others telling you that you are not.

Change the example to public speaking. I may be able to speak fine alone in my room, but that has little to do with my ability to do in front of others.

For MBlume, learning how to do the correct body language (of that character) in front of an audience is only a little different than doing it correctly alone. Learning the right body language of an alpha male is much different when in front of attractive women than when alone.
