That is what I said to myself, over and over, when a so called close friend who knew about my transition, decided to stand up in the middle of a pub and announce my secret to all. I was made aware of theis by a real friend who rushed over to warn me. To say the least I was, and still am, in deep shock. However I am very lucky to have female freinds who love me and care about me. My advice is, if you feel, even vaguely that you should not say anything, its safest to keep quiet, because some people can be very deceptive, and have motives which are only understood to them.
