Chloe, a girl on the front row

Chloe is a slim, pretty girl sitting on the front row in front of your desk. most of the students appear to be enjoying your class but she appears distracted. Never raising her hand to answer a question. Always taking just a little too long to laugh at one of your jokes. You begin to wonder why.

You catch her eye and she blushes. "Chloe what do you think?" She blushes harder.

"I'm sorry sir, could you repeat the question please?”

"If you see what appears to be a barn in a field and thus form the belief 'There is a barn in that field'. Are we right to say that you 'know' that there is a barn in that field?"

"Yes sir, I think so"

The class continues and Chloe appears engaged for a while, but soon returns to being distracted. She appears to be playing with something under her desk. Intrigued you decide to sit at your own to get a better angle to see under hers.
