"You have the social skills of a cardboard for someone who has lived for almost a thousand years."
"I really hate that that statement is coming from you, someone who is supposed to be socially impaired."
"Oh, I have actually quite mastered my social skills, Aerith."
"...I hate that I think you might actually be right."
"I also happen to overhear back on Theran that you didn't have any friends growing up."
"Just shut up. You don't have friends either."
"By choice."
"Shut up."
It is true—Aerith did not have any friends growing up. She was surrounded by people, true—but none really understood her. Even at the earliest of her age, she knew she was different from the other themarians.
Her older brother was the same; which was quite awkward for the Royal family who were, for lack of a better word, extreme with their beliefs that themarians belong only to Theran. They have this weird antipathy for the outside because they think the rest of the Universe is just one big pile of junk.
