WHY ARE YOU EVEN HERE!?

Tuesday: ... I wanted to kick a couple of students (well, one in particular, "C," plus those she was talking to) out of my class... OUT, OUT, OUT! They/she didn't do the reading (again), but wouldn't stop talking while their peers were holding discussion.

The first time they were whispering to each other while the rest of the students were talking, I looked over, and told them that it's really hard to hear when others are talking at the same time, but if they had something to share, I'd love for them to contribute. Silence. The second time, I just looked over and said "GUYS". Silence. I told them to get into groups of 4, so that they could help each other form "researchable" questions about their own topics of interest, and when they all came back together, their group was STILL talking (even though I'd put "C" into a group with others that she doesn't normally sit next to). I called their group out first, and asked each of them by name what their research topics were. Of the four, I received 3 serious responses, and one "ummm... I'm not interested in anything."

I wanted to say something snarky, but I just said, "alright, you keep thinking on it, and we'll come back to you." I went around the class; everyone had a topic that was nearly researchable, and we worked as a class on those topics which were a bit too broad to cover in 7 pages. All the while, "C" was whispering back and forth with her neighboring student, and I'd have to look over at her and ask her to stop talking. After the rest of the students were satisfied with their topic choices, I looked again at "C," and asked if she had a topic.
"ummm... the illuminati."
...
I said it would be interesting, but it's a bit broad, so I asked her why she chose that topic and what she wanted to know about it.
...
"ummm.... " she seemed to draw the 'm' out as long as possible before she smiled, shrugged, and said, "dunno."
...

"Alright," I said (and shrugged), "If you don't care about your own work, I suppose I shouldn't worry about it either." Then I looked away, dismissed the class, so that they could use the remaining class time to work in the library, and started packing up my things.
