The excited upperclassman

You walk over to the girl waving you over. She grabs your hand, and shakes it. "Hi, I'm James!" she says, introducing herself, "Thanks for coming over!"

"Oh, uh, why did you want me to?" you ask, not sure why she would want to talk to some random first year.

"Well, I've always thought it would be fun to show somebody new here around, like a proper sempai!"

"A proper... what?" you ask, but before you get an answer, somebody from across the table interjects.

"She just wants a friend who doesn't know that her name is-"

"Shut it!" James says, and you suddenly see that the goblet in her hand is crumpled. You check your own, to see if it's made of tinfoil or something, but no such luck.

"I think you scared your friend." the girl across the table laughs.

James looks over at you, and sees you staring at the goblet in her hand. "Oh, this, uh, don't worry, they're not that strong. You'll probably be able to crush one yourself before too long." She pries it back into a rough goblet shape with her fingers. You can't help but think back to your handshake. Maybe you should go?
