Jeff and Jill went back to their room. Jeff opened the door first. It was the same as usual.
"Wait a minute..." said Jeff.
"I was expecting that my room would change, but it's all the same."
"It's my room!" said Jeff. "Or our room, anyway. I think this perception of reality is just that. A perception. Everyone except Mom remembers two people, but we still don't have two rooms, or wardrobes, or anything like that."
"Wait a minute!" said Jill. "We don't, but we can fix it so that we do. Look, when you change someone's age it'll change their clothes, too, right? So it works on inanimate objects. Like rooms." Jill started searching through the settings on the Chronivac and finally said "I found it!"
Jill pointed the Chronivac at the room and it seemed to shimmer. Things rearranged themselves. Somehow the room was larger. It now had two beds in it and from what they could see, the closet was larger. A nearby door outside the room had moved--the storage space next door must have shrunk. "It worked. We just have to change the school next."
"I bet you want to try being a girl for a few days," said Jeff. "I'd never admit to anyone else but I think if I was the girl that's what I'd do. It's hard to not be curious."
"You're right... Jeff. You're thinking just what I'm thinking. But it's strange, I don't feel girlish," said Jill. "I'm me, I'm Jeff, no matter what people call me. I just have breasts now. Here, take a look." She began to take off her shirt.
"Wait!" said Jeff.
"You don't... Oh, I see. Maybe it's a bad idea. I know I'd be embarassed to see a girl show me her breasts like that even if she is me... Even when I was dating Lucy, she wouldn't just strip in front of me for no reason.
"When you were dating Lucy...? I was dating her! Well, I guess you were, since you're me--we both were. It's just so strange," said Jeff. "If I look at you it's like a mirror with a few big differences. I could imagine you being my sister, but I don't remember having one, and real opposite sex twins don't look alike except by coincidence."
"And you. You're more like a mirror than I would be in a mirror. I mean, I have breasts, and no dick. But you're just what I remember in myself."
"So how long do you want to do this?" asked Jeff. "A week?"
"Sounds good," said Jill. "Wait... I bet you just guessed that because you know how I think."
"Right the first time!" said Jeff. "So anyway...."
