Tea Tree Oil
By Silver Sailor Ganymede

It was just another normal day and Tomo and Yomi were sitting in Chiyo's room. The original plan had been for everyone to meet up, but Kagura, Osaka and Sakaki all had colds, so it was just the three of them.

Tomo had been complaining all morning while refusing to actually do any work, so Chiyo had kindly suggested they take a break and gone downstairs to make some tea. That was why Yomi was currently sitting there feeling as though she wanted to kill Tomo; she was worse on her own than every other annoying person on the planet put together, Yomi decided.

"I wish Chiyo would hurry up with the tea; it's freezing in here!" Tomo whined.

"Tomo, you can't be freezing; you're practically falling asleep under the kotatsu," Yomi pointed out.

"Nah I'm not," Tomo protested, stifling a huge yawn as she did so. "Hey, here's Chiyo with the tea!"

The younger girl smiled as she set the tea down on the table and then sat down herself.

"I hope everyone likes the tea; I guess we all need a short break from our studies after all," Chiyo said.

"Yep, we definitely do!" Tomo exclaimed before Yomi could point out that she'd done no studying whatsoever since they'd started. She really needed to confiscate Tomo's manga collection – and read it for herself, but that was beside the point.

Tomo took a sip of her tea, then an almost unnaturally pensive expression – well unnaturally pensive given that it was Tomo, came on to her face.

"You know, I was reading something when I was looking at make up the other day, and…" Tomo began, but Yomi interrupted her.

"Don't even say it Tomo: the answer is no, they don't put tea tree oil in tea," Yomi groaned in utter exasperation.

"Are there trees and oil in the tea then?" Tomo asked, and Yomi growled in annoyance at the girl.

"Do you want me to hit you?"

"Sure, I love pain. You know how much of a marsochist I am," Tomo grinned.

"It's 'masochist', Tomo… and do you even know what that means?"

Tomo, however, ignored her question, "Heh, what's the bettings tea originally came from Mars, eh Osaka?"

"Tomo, Osaka isn't even here..." Yomi sighed. "Everyone other than me, you and Chiyo is ill."

"Reallly?"

"No, they've all been abducted by aliens," Yomi drawled sarcastically.

"You're wrong!" Tomo jumped up in the air suddenly, pointing at Yomi with a look of triumph on her face. "Osaka is here; she's just taken over Yomi's brain, that's all!"

Yomi and Chiyo both shot Tomo a look of complete confusion and the other girl sat down, pouting.

"Well actually Tomo, tea tree oil, which is actually called Melaleuca Oil, is native to the northeast coast of New South Wales in Australia. It's taken from a planet called Malelueca Alternifolica, and really has nothing at all to do with tea. So don't worry, there's no tea tree oil in your tea," Chiyo explained.

This, naturally, went right over the top of Tomo's head, leaving the girl wide-eyed and shaking.

"Osaka's got you too!" she shreiked.

"More like the Martians have taken over your brain, ms 'marsochist'," Yomi muttered, sipping her tea and wondering how long it would take to get rid of her Numbnut - or rather Tomo-induced headache. Maybe another cup of tea would help…
