In Kindergarten there was this fat Italian kid that bullied me with authority, he always was throwing toy cars etc at windows, called the Kindergarten teacher and told her it was me, and she always believed him, I hated him and the Kindergarten teacher.
Then when we were in elementary school, my mom still invited him to my birthdays as his mom and mine were friends.
And I had this window in my room, you can complete turn to the opposite direction, hard to explain on english.

I made him look out of it, and pulled the window to trap him and he thought he was falling from the roof and screamed, after that he always was scared of me, valuable lesson in life that shaped my character and lust and enjoyment for revenge.
