You wake up this morning and saw, that reality changed. You go out and met your petite, short little sister. No, wait, she is not petite anymore, not short anymore, she even does not look like your younger sister. It is tall, strong, confident, muscular, buff young woman, who look even older than you, more mature than you. And she treat you now as her pet, toy and plaything. She looks down on you. And she does not see any changes, she does not remember that something was different before. All other world also did not realize any changes, as all this was always like this.
