"You know..."

You walked beside Senku as the two of you gathered minerals along the riverbank.

"I've never actually seen you get angry."

"Hm."

He kept filling a small leather pouch with rocks. "That's because I don't waste energy on it."

"So you've never argued with anyone?"

"I argue."

"You mean debate."

"Same thing."

"No, it isn't."

He shrugged.

"Close enough."

You narrowed your eyes. "...I'm going to make you mad."

"Tch."

"Good luck."

The attempts started immediately. You hid his favourite piece of quartz. He found it in under a minute.

"You always hide things in obvious places."

You swapped the labels on his jars. He sniffed each one.

"...Cute."

You purposely gave Chrome the credit for one of Senku's inventions. Chrome panicked.

"It wasn't me!"

Senku just sighed.

"Obviously." —-—-—-—-—-—-—- Three days later...

You flopped onto a log.

"...Why are you impossible?"

"I'm statistically annoying."

"I know."

"I've been trying to make you argue with me for days."

"And?"

"Nothing!"

"You don't even react!"

Senku looked up from mixing chemicals.

"...That's because none of those things mattered."

You blinked. "So what does matter?"

He thought for a second.

"...Breaking equipment."

"Endangering people."

"Destroying knowledge."

"That's about it."

You frowned. "So if I called you an arrogant jerk..."

"I've heard worse."

"If I said your hair looks ridiculous."

"...Objectively false."

"If I said chemistry is boring."

"Now you're just lying."
