Open Question: trans-sexual visiting -not sure what to tell the kids?

An old friend contacted me out of the blue a couple of weeks ago, i hadn't heard from them for almost ten years. What was a he and is now a she was coming down to London because she had an appointment with the gender clinic, we met for coffee and I accompanied her to her appointment after I adjusted to my initial surprise at the change it was cool. Then a few weeks later she called me again and explained that her next appointment was at 9.30 am and that she could do with having somewhere to stay the night before. Now I'm totally fine with the trans-sexual thing and my kids meeting her, in fact I think its good that children have a varied experience with lots of different people. but I'm not sure what I should tell them before hand -if anything. To me its very obvious that she has male characteristics, I'm not sure how obvious this will be to the kids -who are 5 and 7 and may not even be aware of subtle gender differences. So should i explain stuff to them before she arrives? Or should I not say anything and hope that they don't notice? or should I not say anything and let her handle it if they do ask -I assume that kids do ask quite often. I don't feel i know her well enough to ask her any of this. I'd like feedback on this issue, I'm not interested in hearing any disparaging remarks about trans-sexuality or my parenting thanks!Read More...
