[Politely, Rei smiles right back. She's glad to help, and if she's guessed right, this girl is slightly older than her.]

I'd be happy to show you, I can meet you any time today. I'm finished with my chores, and my housemates are all out. Name a time, and I'll meet you in the plaza.

[If Rei could verbally shrug, she would]

Fortune telling? Well, it depends on who's doing it. For me, I take something of yours. A hair, a bit of a finger nail, or a piece of paper with your name on it, then I burn it in offering to the spirits. After that, it depends.
