don't know, maybe the HM's are not suspecting/dreaming of a person in that situation being in their midst (gender reassignment) and so are oblivious to what might be obvious to us.. i can fully understand why nadia wouldn't say anything to everyone, as explained by englishmisfit post #45 -
i've worked gay/whatever you like club nights where there have been a good few transsexuals turning out - some very good, some not so good! but i could always spot those who were really men/born men. interestingly, none of the males i worked with could spot em, and were always suprised!
