Okay, so I really didn't come out and tell my sister "hey, I'm transgendered" but she knows. She reads everything I put up on Facebook and never once has she complained or confronted me about it. She knows I'm polyamourus, too, and doesn't care.
My sister has got to be the greatest person in my life. She's there for me no matter what. She lets me rant and rave, or cry. She doesn't care I'm bisexual, transgendered, and polyamourus and is even able to help pull me out of a funk by a simple line of "you should marry a dog, they never care if you have more than one".
I love her so much and I'm glad I know that I'll at least of her to support me if things go bad with my parents.
