Ungrateful Little Bastard.

  At the age of thirty one  , he walked across the classroom and sat on the teacher's desk. His desk. The class was empty so he let out a sigh of pain and touched his right ribs , where he had received a blunt attack the night before. Looking around the room , he felt a certain level of pleasure and satisfaction. He always wanted to work as a teacher. Another sharp pain in the ribs made him close his eyes for a few seconds.
 "Are you alright , teacher?" a teen girlie voice echoed through the room as he raised his head to greet his first student.  He always wondered what he looked like to them  , his kids.
"I'm just fine , thanks , Débora. How was your weekend?" asked the teacher with a professional smile.

   The girl went on about her uneventful two days of weekend , João payed attention to every word. He knew that she would mention what he had done last night. It made the news!
"You won't believe , teacher! A group of drug user has been harassing my neighbourhood for days . The invaded my granny's house and killed her dog! They even sold drugs to some of my neighbours! The last drop was when they started to throw parties oon the street! They would call everyone they knew. Drug dealers , users , the whole motley crew!"

  "Did you call the police , on them?" asked the teacher with a polite smile.
"No!" said the girl." I did worse. You know how people say that , now that everybody knows werewolves are real we can , kinda, rely on them to sort some things out? Well...I know a guy who told me he knew one of them and that his friend was kinda into helping people in need. Can you imagine that , a werewolf vigilante?"
 The teacher faintly nodded and let the girl continue.

  " He told me to open my window and blow this weird whistle! It looked like a dogs's whistle but with some carvings on it. I already returned it to my friend. Anyway. I did it. Last night. And I saw it."
"What did you see?" asked the man a bit anxious for the description.
  "All those drug addicts...they were having an orgy , right there on my sidewalk. I swear to god I could see two of my childhood friends there with them. Stoned to the bones! I blew the whistle and , five minutes later , from the top of my house , a large black animal leaped into the darkness and , in minutes , was on top of the leader of the group. A dreadful guy named , Ronaldo!"

  The girl made a pause and sat at ther desk  , her eyes were glued to her teacher's face and his to hers.
"One of the dirty guys grabbed a pipe and attacked the werewolf. It grunted in pain and anger and slashed through all of them in a matter of seconds! It was ..."
"Fantastic?" said the teacher with a curbed enthusiasm.
"Terrifying!" said the girl. "never in my life had I been so scared!"

 "But your neighborhood is free of those guys...You should be happy." said the teacher.
"I would be happy if the werewolf had not eaten their flesh right in front of my eyes."
 The clatter of the steps of the other students broke the conversation vibe. The teacher laid back on his chair and supressed the pain he still felt on his ribs.
