To my kids it was easy just told them I had a girl brain and a boy body. Then that I want to be a girl and get a girl body some day... They know my new name is Jerri to most people with the correct spelling. Their school is being told tomorrow morning chat with head teacher should cover it.
For work I did a wall of text as I like them all and consider them friends. Laid out all the pieces of the puzzle then assembled them. Easier than giving answer then explanation.
To my priest today I only had like 60 seconds before he had to do next mass so gave him a 2 parter. Changed my name to Jerri and that it's short for Jerrica. Gave him a few seconds to put it together then told him I'll see him later. Caught him again after mass and he was surprised for sure as I'm the first he's ever met but happy I was able to tell him. Must admit I was initially expecting some good old fashioned fire and brimstone but he was great. So all seems to be fine with me and church coolness (not everyone's cup of tea but I like it)
I like to use the name thing to make them think it before confirming it. After that I'm happy to chat about anything especially my history. Any honest question I'll try to answer the same way.
It is different for them but also fun as they learn more about me. They enjoy learning and I enjoy talking so everybody wins
