Don't ask don't tell
I haven't yet told my friend Louise that I'm trans so when she brought up the issue which involved a TED talk she had seen featuring a transwoman, I was first taken aback and then tempted to say something. Still I held back because I was curious about her blunt and open take on the subject without needing to walk on eggshells around me. She said she wasn't a social justice warrior although she isn't at all against trans people. At 61 she forms part of the population that didn't grow up with knowledge of this issue and like me grew up in the dark. For this I cannot blame her.
The topic had come up via a more general discussion on tolerance and diversity training in the workplace which she thought was perhaps a bit much. At the very least it was nice that she will be receptive when and if I tell her.
