I believe that a big fear of mine is not having anyone match my exhibitionistic energies after having displayed them. 

I also believe that's why when I'm excited about something (book, movie, event, subject, etc..) I'll display right about the same amount of enthusiasm people in the room show to the thing I'm excited about, even less I would say.

 Other times, when I feel like I can't keep repressing my excitement, I just display it a manner that makes it impossible for anyone to match. Then I don't have to wonder if I'm going to be rejected or not.
