"Of course I am," says Robin.

"Good, I haven't killed anybody with laughing so far and don't wanna start."

Ethan grins.

"So what class do you have after lunch?" Andi asks Robin.

"Archaeology. I mean, English."

Andi giggles. "Us too, that's cool."

"Hopefully they'll keep the severed arms to a minimum."

"But who doesn't love a good severed arm?"

"The people the arms belong to, probably. The better the severed arm the less they like it, they probably wouldn't miss a terrible arm that much."

Robin starts giggling again.

"Au contraire," says Ethan, "I'd think a badly severed arm is more worth complaining about. All that mess and unnecessary discomfort."

...Robin sporfles.

"No, you have to distinguish between the arm, and the severing," says Andi. "If the arm is good and the severing is bad that's the worst for the arm, um, donor."

"Pfffffffffffff," says Robin.

"I think our girl's sprung a leak," remarks Ethan.

"I don't have my bicycle repair kit, can't help you."

"Well, nobody cut off her arm, that'll only make it worse."

She thunks her forehead against his shoulder and cackles helplessly.

"I don't have my hacksaw either anyway, I'm going to get marked down for coming to school unprepared."

Giggle giggle.

"You've gone and done it again. She'll never recover at this rate."

"Ooooops?"

"Dying of laughter is very uncommon."

Robin continues to snicker.

"She may not die of laughter, but she might die laughing," snorts Ethan.
