I have a particular student (let's call him "B") who is among the most socially retarded people I've ever encountered. B has grated on my nerves all fucking semester, constantly interrupting me and the other students with his endless, monotonous monologues that are only tangentially related to the discussion, but mainly serve to confuse the other students. On more than one occasion, said ramblings have prompted me to blurt out, "What?," with an utterly baffled and exasperated expression on my face. The other students snicker, but B is oblivious to them because he believes what he is saying is brilliant and breathtakingly original. His eyes dart around the room to see if anyone has noticed and is impressed with said brilliance, but all B gets for his efforts are bored expressions, fidgeting, and awkward silence.
It's embarrassing and sad, really. I try to ignore B, but he always has his fucking hand up. It's painfully obvious to the other students that I'm ignoring him, but most often they are no help either because they just sit there and stare at me, waiting for me to give them the answers or break down and call on B. I must admit that I get some amount of sadistic pleasure intimidating B. He's always coming up to me after class and apologizing for interrupting or laughing at something only he thinks is uproarously funny.
B is incapable of talking like a normal human being. His language is obsequiously formal, which makes interacting with him all the more difficult and awkward. Then he bows (yes--bows!) at me like I'm some sort of latter-day Kung-Fu master, and he is my grasshopper. Muttering to himself, he walks out of the classroom.
