There is something I really need to show you. Remember how the last time we talked you thought my voice sounded funny? Well I've been through some changes.
Yes, that really is me and it's all natural. Turns out I caught some disease and made me into a girl. It isn't bad, in fact I love it and you finally have the daughter that you always wanted. I should be home in a few days. So maybe we can spend time together. I want to tell you about a boy I met.
P.S. I don't know what you should tell Daddy.
