re: Do you know anyone who is trans?

Yes, someone I worked with on a project well over a decade ago in Colorado. It was a controls project and she is an excellent coder. I had suspicions the first time I saw her. I asked one of her coworkers who acted as though he wasn't sure but I think he feigned ignorance. Eventually, she did tell me she was her biological children's father. I feel like those kids are going to be a bit confused though I guess they are adults now.

If you wonder why I use the pronoun she, it is simply because I initially knew and worked with his person as a female remotely and only met her months into the project so I think of her as a she. This was well before all this was accepted and she was not demanding or in any way overt or demanding. She looked like a sort of plain to slightly homely tall thin girl. I have no idea if the plumbing matches the pronoun nor do I want to find out. Have not spoken to her since that project which ended probably 15 years ago.
