A Bit of Revenge
I was a volunteer assistant teacher for first graders. I had one student who was one of the smartest in the class but was also really mischievous and kind of mean.
One day, since my desk was the table behind hers at the back of the room, I just started taking the pencils she was using and hiding them behind me whenever she would look away.
It went on for about an hour. She was digging through her pencil case in confusion and looking under her desk because she knew she had to have been writing with something, but her stuff was just magically disappearing.
It didn’t take her long to realize it was me, and she turned around and was absolutely livid. I just smiled and gave her back a bundle of about ten pencils. Story credit: Reddit / asknotthesparrow
