"We should probably also figure out who's paying for what."

"I'll get dinner, you get the movie, other way around next time?" he suggests.

"Sort of depends on whether you're looking for, like, fairness or relative advantage, because my mom is independently wealthy and I could just pay for everything but if you'd rather divvy it up I won't argue."

"And here I was thinking that 'analyze our relative financial situations to determine who can best afford it' was a needlessly complicated approach. Feel free; I think it's entirely fair if you're offering."

"It's probably more complicated in most circumstances," she agrees.

"Yeah."

And then the teacher arrives and requires of them that they math instead of talking.

That is acceptable.

After class when they can talk again, Edie asks: "So, I've met your mom--would it be premature to ask if you wanted to come over after school to meet mine?"

"Not at all!"

"D'you wanna come over after school and meet my mom?"

"Sure!"

She grins and impulsively hugs him.

Hugs!

Eee hugs. 

Okay they should probably go to their next classes now.

Yeah.

The rest of the morning goes by fairly inoffensively. They are still doing badminton in gym.
