They say power corrupts, and absolute power corrupts absolutely. It turns out, for some people even the tiniest bit of power can corrupt. There was always that one kid who took his job as the hall monitor a little bit too seriously. Not everyone grows out of that as an adult. One reddit user asked:
What's the smallest amount of power you've seen go to someone's head?
The answers gave us several migraines from the amount of times we rolled our eyes. .
A girl I worked with was promoted to assistant manager at pizza shop because she was the only one there that was 18. She went from an okay worker to not doing anything and making my time there a living hell. I eventually quit and was asked to come back after she was fired.
5 years later, I got a random Facebook message from her apologizing for being such an a**hole during that time.
Probably to my own head. When I was about 8 years old I was asked by my teacher (because I was being well-behaved I assume) to stand by the whiteboard whilst she was talking about something and write the names of people who were talking/acting out on the board. I went mad with power and wrote people's names down who just looked at me funny.
