When Invention Meets Reality

What would Thomas Edison say and how did the famous inventor come into this?
I have written several times of the chats I have with the person who has known me the longest as a transgender or cross dresser back in the day. He went deep into the closet and obviously I didn't. At times I think he works way too hard to justify his decision. None of my business until:
Recently he mentioned inventing a female persona. (Not specifically aimed at me.) I replied "what if it is not a invention?"
Obviously I believe a transgender or transsexual person is not inventing a gender. They are born with it.
Which brings up another question I asked myself. When did I know when the feminine me was not an invention.  Of course I can not come up with the exact day but as I have written before, I do remember when the realization swept over me I was in the right place.
The sensation was one of a deep realization that all was right with the world. No more in fighting.
I supposed you can say at that moment, I knew I wasn't an invention.
Reading my blog, you all know I'm overjoyed at the realization which most likely had been with me all the time. I was born into my transgender reality.
My worry is my friend will spend the rest of his days in the futile attempt to rationalize his reality.
