An Optimist and a Pessimist argue in front of Celestia

After seeing all the arguments about humans in Equestria and the morality of ponies, I decided to take that argument to Equestria as well.

A pessimist named Robert Anton and an Optimist named Fujiwara Kaito suddenly find themselves next to each other in the middle of Canterlot's throne room.

Through the magic of friendship, Robert and Fujiwara find out that they hate each other... a lot.
