Want to teach philosophy

You teach philosophy. It's a decent job. There are lots of smart students and a few cute girls.

One day, one of your students, Michelle, lingers after class. She's shortish, a little chubby. She wears her long, straight, brown hair out every day. It's never clean. But she's very smart.

She asks if you'd be willing to help her with a problem sometime later in the day, around 4:30 p.m. or so. She says it's an ethical issue.
