Well, I sent a letter about my transition to the company I work for remotely (it is a fashion company based in San Fran) and they changed from my legal name to my preferred name in our computer system literally fifteen minutes later, LOL.  "Not a problem!" was the response, haha.  Glad I worried for nothing.  Like, literally, I'm glad that my worrying about doing this was over nothing!  

  If only all my "coming out" moments were so chill.
