"What's the square root of 522,443?"

"2."

An explosion of air escaped, followed by a laugh. A guffaw. Ami guffawed. Was, in fact, still doing it.

Makoto leaned into her palm, watching with amusement.

"722.80." Ami jabbed Mako's shoulder too hard. "Rounded."

"Okay."

"Check! Who has a calculator?" she demanded of the bar.

"I trust you."

"I am in complete control of my mental faculties."

"Clearly."

"And not at all drunk."

"Of course not."

"Thus I should be allowed another."

"Nope."

Ami protested by doing more math at Mako. Mako regarded Ami with indulgent affection and waved off the bartender.
