The following is a word from our narrator, Ms. Narrator.
"For those of you who haven't figured this out yet, Robin picked up the wishing rock which Jon had gotten from his grandfather."
"Robin's most recent wish, that he would be able to pick up a chair just like the girls were able to, triggered several changes in him."
"The trick as to why the girls were able to pick up the chair and the stronger boys couldn't is due to differences between the bone structure and distribution of mass between boys and girls. Basically, due the needs of child birthing, girls hips are different than boys. Additionally, girls have more mass below their waists than do boys. Maybe my brother knew more than I thought when he called me Thunder Thighs; but I digress."
"Robin's wish made several changes in Robin."
"First, his bone structure changed from that of a boy entering puberty to that of a pre-puberty girl."
"Second, the male hormone mix in his body changed to a female hormone mix, and his body changed so that it would only produce this female hormone mix."
"And finally, third, an anti-male hormone was introduced into Robin's system. This hormone, never before detected, worked to undo the effects of male puberty upon Robin."
"Now, if left unchanged, these changes would, by his fifteenth birthday, change Robin from a 'late blooming boy' into a near female whose body generally conformed with that of the his female siblings, on their fifteenth birthday."
"Any of you thing that these changes were all that would happen to Robin? Raise your hands."
"Shame on you few who raised your hands; you should know better."
"That said, back to the story."
