What the Face

Recently, this photo was taken of me.  I was unaware, and surrounded by a group of people that I did not know.  Upon seeing this photo, I was overwhelmed with the need to address a phenomenon that has been building over the last ten years.
Now is the time to acknowledge this one thing that has been haunting me:
  I have bitchface.  

This is not something that is easily understood by my peers, to whom I constantly appear as such:

Apparently, to the general public and strangers, I carry such a heinous look on my face as the previous photo; making me wholly unapproachable to anyone that hasn't been previously acquainted to my pudding-filled personality.  It's refutable to people who know me, they all say that's impossible.  But I've been told more than once.  When in presence of unfamiliar people, I somehow express a look of seething disdain and unexplained annoyance.   

An example:  When I lived in Spokane, I frequented a yoga studio downtown.  One of my dear friends, Kirsten, recommended it to a coworker of hers.  She sent her there, also telling her to introduce herself to the little asian girl (ahem, superfriendly me!) who would inevitably be practicing there as well.  This coworker went to yoga and noticed me plainly, but she didn't say anything.  WHY, I would ask Kirsten later??  

BECAUSE I DIDN'T LOOK FRIENDLY. 

Well, scoff.  I dont know!  How does one change the way they naturally hold their face in neutral?!  Is there a class I can take or exercises I can do?!  Is this why I have always felt so safe in foreign countries and never get bothered on the bus?  What am I supposed to do?!  Walk around in my life with a dopey grin on my face?!  Is that what YOU DO?!
