Went to lunch with a group of my closest co-workers today, sitting at a table nearby was a young "trans-man"... and one of my male counterparts said, 'How do you address somebody like that? Sir, mam, he, she, etc...' I Attempted, to explain that the best way is to considder how they are presenting, and address them as such. If you are confused, ask... they might be offended at first, but theyll apreciate your attention to their feelings. They were all surprised by my particular level of insight into the matter. Except for the one female in the group, that knows about my alterego Jordyn.
