Well, it is pretty far fetched if you really think about it. I mean, a girl born into a boys body, to those not living the experience it probably sounds almost like science fiction. So we're special
I wouldn't blame them too much if I were you, and I wouldn't blame yourself. Something I've noticed as I have started associating with other Transexuals is in their effort to "act" feminine they overdo it and look absurd. If you start behaving that way in an effort to convince your people, I would imagine that will just increase their resistance. For me spending time with other women my age has really helped. Just be yourself and let it come. Nobody ever taught us how to be girls, we were taught that boys dont cry and boys are tough blah blah blah. The power and depth of socialisation is incredibly strong, and we have been socialised as boys, and they're used to you as such...give yourself, and them, time.
