I dont agree with the notion of the OLD and the NEW person. We are one in the same.
My mother told me that my younger brothers greived my "loss", and then they didnt talk to me for almost 20 years....
After the death of the oldest of my 3 younger brothers, we met again at the wake.
I have the same sence of humor I did before.
I have the same hobbies, if not more.
"I" really havent changed that much.
Welllll. Except for my bountious rack

Actually its more a change in perception. We are back talking and doing the same things we did BEFORE I transitioned.
Though they do open the door for me

Dont make it a sad occaision, but relax, be your self and smile and laugh!
Today is the start of the rest of your life! Enjoy it and let others see your happyness!
