"OK" Ginger sighed "But be careful not to wish to forget anything again. Right after the change, there were three big wishes made by billions of people together. One, no wish can change a person without their consent. Two, no wish can be made that would lead to mass death. Three, buildings and other places held in common can only be changed by a majority of their users wishing together. These wishes could be un-wished, but only by a greater number of people. Unfortunately, some one had already changed our school before the Big Wishes."
"So why are we still in high school? Can't we just wish to learn everything we need?"
"Hey, if you want to wish to be out of High School be my guest." Ginger snorted. "It's just that a lot of people wished to be this age, and High School seemed to be a good social setting. Wanna have sex?"
"Uh, what?"
"If you wanna do straight sex it's your turn to be male this time."
