Angry

Aristotle said that it is easy for anyone to become angry, but knowing the right person, reason, time, and degree are not easy.
Somehow, Plato always knew.
“Why are you always in that dark cave?” shouted Plato.
Aristotle tried to hide something behind his back, but Plato shook the boy until a set of geometric forms fell to the ground.
“Those are mine!” growled Plato.
“They belong to Pythagoras!” whined Aristotle.
“I was respectful to my teacher,” said Plato.
“Oh, sure,” retorted Aristotle. “He probably drank the hemlock so he wouldn’t have to teach you anymore.”
Plato slapped Aristotle hard.
