What are the rules?

Angelina was sitting peacefully on the couch, munching on some chips when Alethea sat next to her.

"Hey", she said.

"Hey", was the answer. 

"Watching TV?", she asked. 

"Isn't it obvious?", she said. 

"Why are you always such a downer? You should be a bit cheerful as you're the oldest, right?", she asked her. 

"I dunno. I've always been like this. You got a problem?", she said, eyeing her. 

"Meh, not really. But you might be able to fit in my house", she told her. 

"Your house? The house where you lived in earlier, right?", she said, "Well, I want nothing to do with the likes of you! I hate you alot, Alethea and I didn't even want you living here with me. But I'm putting up with you and it hasn't even been a day and I am so fucking tired already!!!!".

"Looks like somebody hates someone", Kayla said, when she heard Angelina raging upon Alethea, while sitting next to them. "What's the problem between you two? Can't you put up with each other just to keep us four happy? I know you don't like each other but really, you're so absurd!". 

"Now you're the one who's siding with the rules of the house!", Angelina said. "You never wanted anybody to move in after you did and ever since Tina and Benedict did, you've been being such a bitch. And now YOU, out of all people, want me to talk to Alethea calmly?!"

She couldn't hold her temper in now and threw the TV remote on the ground. She threw a cushion at Kayla's face and then went into her room, locking it.

"Why'd ya say all of that? You never liked me in the first place", Alethea said later when things calmed down a bit, "And what was that thing about the "Rules of the house?".

"Well, it's nothing", Kayla said, "And don't think that I like you even a little bit!. Nobody in here likes you and Angelina is the perfect example of that". 

"Well, if you don't like me even a little bit, then why save my ass there?", she asked her. 

"Just 'cause Angelina is one hell of a person and when she gets mad, nobody can save you from her, except Tina", she replied.

"Oh yeah. I see Tina has alot of superiority around here", she said, 

"You're older than her, right?. So, why can't you handle stuff like she does or is it just that nobody listens to you?".

"You know what? Turns out, you're such a piece of shit. And here I was trying to befriend you for a while. But it looks like only some people can only ever talk to a shit like you", she said.

After throwing all those insults at her face, Kayla got up from there, regretting her choice to even sit with her in the first place and going outside in the garden to dance to some song.

In the evening, when dinner was being eaten, Tina asked everyone about their interests. Aroma said drawing. Benedict said something about the medical field. Kayla said dancing. Angelina didn't want to say anything. And when it was time for Alethea, instead of her interests she said: "What are the rules of the house?". On that, Benedict choked on her food. 

"What did you say?", she asked her. "Who even told you that?".

"Oh. Well, me and the girls were talking and we stumbled upon that word", she replied. "Well, what are they? Tell me".

"Well, they're not something important. So, you shouldn't know", Tina said, reassuring her. 

"Tina, that's not true", Aroma said, "You gotta tell her".

"And what happens if she tells her?", Angelina said. "It's not like she's even gonna follow them!". 

"So, you're not gonna tell me?", she asked. 

"No", Tina replied, calmly.

"Fine. I'll just find them out myself", she replied.
