Q: Ok, I hope this is not presumptuous but I have a general LGBT question. What is the proper etiquette when interacting with a transgendered person? How do I know what pronouns to use, etc.? Also, you've shed some light on this already, but any other etiquette you'd like us to know about how to best interact with gay couples/families? (i.e. introducing the wife)
A: Transfolk- chances are everyone had had an interaction with a trans person whether they know it or not. I am not trans and don't speak for them, but a good resource is

I believe that respect goes a long way in avoiding misunderstanding. Using "it" is never appropriate for a human being.
I really don't think there is a lot of etiquette. Treat us like you would your other friends. Don't be rude (ie- can I watch? Who is the man? Etc) and you'll do fine. Oh and as for the boyfriend vs partner vs husband/wife. Follow cues if you don't know.
