noun
Something that causes anger despite obviously not being worth getting angry about.
“Wait, you did what?" asked Josephine, her voice suddenly cold.
“I… I drank your soda from the fridge,” said Alesha. “It’s okay - I got you another one!"
Jo leaned in, her eyes narrowing. “But what if I’d been thirsty in the meantime?” she asked. Hearing herself, she stopped. She leaned back and took a deep breath.
“I… I’m sorry?” said Alesha.
Eyes closed, Josephine said, “Alesha, I’ve had a rough day. I know a soda doesn’t really matter, but you taking it is a ragespark. I need you to leave me alone while I calm down.”
