"Wait a minute," Jon objected. "According to you, at one time there were no such sexes as male and female. Instead there was a different set of three sexes called remmas, tessams, and chadras. The stone can't make a change like that. According to grandpa's note, its range is only a few miles."
"Oh Jon, you have so much to learn," his mother began. "One approach is to wish that the first ten or twenty people who leave the stone's range would repeat the wish, and that one wish of theirs would be granted. Of course, that means that the first ten or twenty people who leave one of those further ranges would also repeat the wish, and so forth. Crossing the ocean used to take a long time with that method, but not any more.
"Another approach is to wish that the stone would transport itself to the north pole, implement the wish, transport itself a few miles south, circle the pole and implement the wish every few miles, then transport another few miles south, then make another circle, and continue until it gets to the south pole."
"Some of the things you mentioned before still seem like an abuse of power," Jon complained.
"Tell me truthfully, Jon; did Karyn want her oversized blonde hair and oversized breasts? No, I guess not. So wasn't that an abuse of power by your definition? You see, no matter how you use the stone, you're altering the natural state of the world and the natural flow of events. The only difference lies in how we each justify ourselves. And who knows? Maybe the natural flow events is supposed to be that you get the stone and the two us decide how to use it."
"None of that gets my dick back," Jon complained.
"Piff, that's easy," his mother stated, waving her palm for emphasis.
"Grandpa said that wishes couldn't be changed, and I've tried reversing some wishes, especially this one, and he seems correct. So how are you going do to it?" Jon demanded.
