I'm told Lynn is the best person to get to work on a task on my project. I talk to Lynn's boss and get Lynn assigned to my project. I call Lynn to introduce myself. I tell Lynn that I was told to get 'him' on my project as he was the best at a certain task. Lynn tells me that she is a she, not a he. (I felt bad.)
Yesterday, I find out that Lynn recently had a sex change operation and that 6 months ago Lynn was actually Leonard.
Still feel bad for the mistake, but at least my hearing was okay.
