Thought "up" was the status quo...

Once there was a little girl named PJ who was quite the exemplary obedient Asian American girl: going to school, doing well in classes, memorizing the multiplications tables when all the other kids in class barely knew how to add (or count), doing "chores" below minimum wage, and listening to her elders.

Except one thing kept bothering her: the toilet, specifically the toilet seat.

That blew her mind.

The End.
