Later that day, there was nothing but silence in the Marsh Residence. In the living room, Stan just stood in the middle, laying on the floor motionless, with his arms open like wings. He just kept staring at the ceiling, with his mind as blank as its paint. It was unknown what drove him to such a position. Maybe boredom.

Then, someone approached him and stopped a few inches by his head. Stan raised his eyes to see who it was. It was Shelly, looking down on him, hands on her waist. She enjoyed that instance. It transmitted an air of superiority.

"Well, well, what do we have here? A turd dropped on the floor." She uttered.

"Haha, I'm cracking." He laughed drily.

And then, remembering his sister's visit to the bathroom and taking advantage of her standing above his head, he fixed his gaze at her crotch.

"Nice view, by the way. Did you wipe that properly?"

"Do you want me to sit on your face, so you can see it for yourself?"

"Oh, knock yourself out!"

An unamused Shelly gave Stan's head a light punt as response. Not strong enough to cause any real damage, but strong enough to be painful.

"Ow!"

"In your dreams, turd."

While Stan sat on the floor and rubbed the top of his head to alleviate the pain, Shelly took a sit on the couch. She grabbed the remote and turned the TV on. Stan's body was blocking the view, though.

"What were you doing there, anyway?" She questioned.

"Uh… just…. musing." He replied.

"Well, then, go muse somewhere else. It's time for my show."

"Urgh. Fine."

He got off the floor and cleaned his behind with his hands, then slapped them together to remove the dust.

"Mom asked me to do some shopping anyway. I'm on my way now."

Shelly dismissively waved her hand. "Yeah, yeah. Whatever."

Annoyed enough, Stan chose to disregard her indifference and exited the house to perform his chore. Shelly now was left alone with the TV.

Half an hour later, Stan returned from his shopping with a bag of groceries in his left arm. He crossed the living room, where his sister was still watching her show.

"Oh. Back already?"

She tried to be cordial enough to acknowledge her brother's presence while not paying too much attention to him. She wanted to keep her eyes on the TV. However, all Stan took from that was her rudeness from before, to which he decided to answer accordingly.

"No, I'm in Alabama."

"Hmph. Little turd. You bought all of Mom's stuff?"

"Yeah, it's everything here."

Stan started to check his items, to make sure he didn't forget anything. Shelly turned her eyes to him for a moment, taking a glance at the bag of groceries. And then, she slapped her forehead as something surfaced in her mind.

"Oh, shit!" She exclaimed.

"What's wrong?" He asked.

"It's that day of the month for me again, and I forgot to ask you to buy—"

Before Shelly could finish her complaint, Stan reached for something in the bag he was carrying and showed it to her. It was a packaging of an item Shelly was familiar with. The very thing she needed at the moment.

"…my… tampons? How did you know?" She couldn't believe it.

The thing was, after Shelly finished her first phrase, Stan promptly put his hand in the bag to get said packaging. He also didn't sound so alerted to her exclamation, like he did the other times. It was like he was expecting this.

It was astounding to see how well Stan knew his sister, enough to be prepared for such an occasion.

"How many tampons have I already bought for you? I know your menstrual cycle like the palm of my hand."

Still baffled, and now mildly irritated by Stan's explanation, Shelly rudely snatched the tampons from his hand.

"…Weirdo."

"Oh, I'm a weirdo for doing a big favor for you upfront?" Stan retorted.

"Asking me if I wiped, buying me tampons without me asking, talking about my menstrual cycle… Who are you, my gynecologist? My pussy's my business!"

Stan rolled his eyes. "Yep. Your stinking, bloody pussy."

"Why, you…"

Shelly was ready to jump on Stan to punish him, but he dashed to the kitchen before she could have the chance. Now finding it pointless, she sat again on the couch and went back to her show. Her brother had been too daring for her taste, this was what she thought while she mumbled about his latest remark.

"It's not stinking!"
