You decide to head home to see what had changed with the changes you had made. The picture of yourself and your brother on the beach in your infancy shows you wearing a one-piece instead of your trunks. Evidently, they had thought you were a female back then. You knew that they now considered you a male, as when you entered your room, you found it pretty much identical to how you had left it this morning, except for a few details: in the drawer where you had kept a box of condoms was a box of tampons and a birth control pill, your swimming trunks had been replaced with the bottom half of a bikini, as had your undergarments, and hidden in the back of one of your drawers, you found a picture of yourself dressed as one of your older sister's bridesmaids. You distinctly remembered that one of her bridesmaids had cancelled at the last minute, and unable to find a replacement, you had offered to dress as a girl to replace her. Your sister was one of your best friends in the world. You didn't like to see her distressed.
So you really were the true middle child: half male, like your younger brother, and half female like your older sister. Wanting to take your mind off recent events for a while, you turned on your games console and began playing a game.
