At first, I was a bit shy to reveal my name, even though I had it in my mind. I encountered several people, mostly lesbians (they outed themselves to me later) who asked me "Are you...changing?"
"Why, yes. Yes, I am. etc etc..."
*
excited voice* What's your new name gonna be?!"
"Beth...Beth Andrea _____."
"Wow!! That's so cool! Are you gonna get the surgery?? Best of luck to you! etc..."
About the 10th person to ask me, I suddenly felt "ready" for work to know. I went in, told the boss, got a new name tag and an appointment with HR. I also started showing my friends at work (and some random co-workers) my new name tag. They accepted it without too much fuss.
It was only a couple weeks later that I got the ball rolling for the legal name change...here in WA it's a simple process--pay the court clerk, get a court date, wait in court until your (old) name is called, the judge asks three questions (two required by law, the third was, "Is this how you want to spell your new name? Be sure, because it will be this after I sign the paper.")...and then it is signed.
Hey Presto! I am Beth...morally, ethically, spiritually, physically, positively, absolutely, undeniably, and reliably BETH!
Yay for me! And I ain't never going back!
