Let's try her phone

You pull out your smartphone and, using an app to mask your number, you dial the digits on her contact information. It rings twice, then there's a click.

"Hello?" comes her confused voice.

"You don't know me, but I have something of yours. I'd like to meet and discuss it. Tonight."

Tonight would be perfect, you don't have work and with the semester wrapping up, all your projects are already done. After a few seconds there's no answer. "Perhaps," you say with firm resolve, "You'd rather I put some of this up on bulletin boards all over campus? Or maybe I can just film it all for YouTube."

"NO! Please don't do that!" she exclaims. After a second, "All right ... where do you want to meet me?"
