Just give her some answers. I believe she wants to know about fans. Tell her about the fans you have around your house, and maybe she'll shut up.
On a positive note, she's a college student, and she's doing her homework. I don't know how many hours a week I get lectured about college students not doing their homework. They're not my kids... they're not my students... but I get to listen to it anyway.
Also... her name is Amanda. I don't know if she's at the head of her class, but she's towards the top of the roster, unless the roster is done in alphabetical order, beginning with the last name. If her name is Amanda Zimbalist jr. she might be at the bottom or the roster. But we have no way of knowing, and it really doesn't matter.
My wife has a niece named Amanda. She's kind of an Airhead, but she's also an Artist. Her mom is an Artist, but she's also a bit of a lush, which is one of the reasons that my Brother-in-law moved into a room in the attic for a while, before finally throwing up his arms and saying "That's it... I'm sick of this shit!" and moving out of the house entirely. So, Amanda's Mom is technically my X-Sister-in-law, while Amanda will remain Our Niece, until she gets run over by a truck, or a bus, or a giant plaster of paris statue she's working on falls over and crushes her in the studio.
Good Luck to you Amanda. We're your biggest Fans... Or not.
