You walk down the halls to your locker, and pull out your Physics textbook, while at the same time opening it, so you can place the TF-Note inside it, hoping that no one will suspect you using it in class. Speaking of classes, you began to notice that there were a lack of other students at the school you arrived at.
Aside from Nat who you just turned into a hot babe, you spotted that no one else was at the school at this time, until you discovered the school janitor who was mopping the floor. "Hey kid, you really shouldn't be here today," he explains. "Why not?" You ask. "It's already time for summer vacation. I have a couple more sides of floor to finish cleaning, and then I'll be out of here completely." That means if it was already summer, then you wouldn't be able to transform anyone that day.
