You look around, what the note said still in your head 'Why am I here, how could I change my parents gender when the only gender there's ever been is male. Well I'm basically getting free stuff so...' something catches your eye 'Book of the Norm' you take it to the the man at the counter.
"So you wish to take the Book of the Norm?" he asked, more as a statement "Anything you write in it will become the norm for the world. If you say that it is normal for everyone to be naked, then they will be. If you say that anthro animals are normal, they will be. By now you get the point, might I suggest that you write in pencil in till you get what ever you write in it just right."
"Rrrrriiiiight..." you say not believing what he said. You take the book back home, just in time for dinner "Welcome home son." said pops "You almost missed, dinner. Sit down." said Dad. You sit down, have dinner with the family and go back to your room with your brother. 'Wonder what I should wright first." you think.
