Looks & listens, perfect attendance, straight A's is a noxious combination when bullies rule the school.  Now a teacher, looking to teach a lesson or two in good behavior in class.  All she needs to succeed is one good Teacher's Pet.
She's laughed at and bullied by some kids.
He takes a wrench from his dad's tool box.
They loosen the chain on the swing and they tell her their sorry for picking on her and invite her to play with them at the swings.  They tell her to use the one they loosened.  She gets on and is smiling and swings quite a few times and then it snaps and she goes flying off and lands on the ground.  She hurts her arm and they're laughing.  "Why would we be your friend?"
She goes home and cries in her room.  Her mom walks in and asks what's wrong.  She tells her kids pick on her.  Her mom tries to explain that kids sometimes act that way, you just have to ignore it.  She tells her mom that she wants to be a teacher so she can put bullies in the time out corner.
There is another room attached thru a door in their class room.
"They didn't install dimmers.  You'd get sleepy."
TIME OUT CORNER.
There is a big tub in the corner with a chair in it.  She tells the teachers Pet to tie his hands to the arm rail.  There is about ten buckets on the floor next to the sink.  She asks the bully questions and when he gets it wrong a kid gets to fill the bucket up with water to pour it in the tub.  When he gets the questions right, the kids "boo" him.  She keeps asking questions.  One time, she asks two questions one after the other, he gets the second one wrong.  He ends up drowning to death.
She makes them put on bracelets and tells them what will happen if I take off.  If I get in trouble you get in trouble.  It has there graduation year written on the bracelet.
"I have a confession.  Before I tell you I want you to know I don't miss him. You're right, Calab moving to Kalamazoo is a good thing.  I was curious and I want to do the right thing all at the same time, is all.  I took my bracelet off.  Please forgive me.  Please, I want to be your pet."
"Well.  Goodness."
"I congratulate you.  You're teaching the others a lesson in betrayal."
She has her new pet die.
That girl doesn't show up for class.
"I hope she doesn't snitch.  There is only one way to find out.  Who wants to solve XXX on the board for us?"
"Those that are in control are the ones that won't allow others to"
