He's one of the most clueless and most arrogant students I've ever known. He's failing the class, as he has finally realized.
He comes up to me in the hallway: "When can I talk to you?"
That was it, no introduction, no nothing.
"You're welcome to come in any time during office hours."
"Well, I'm really busy."
"You can also make an appointment if office hours don't work for you."
"I could come in Tuesday at one or two."
"I teach at two, but I have an office hour at one. Come in then."
He nods, sort of, and walks away.
My office hours, as you might guess, are on the syllabus. If this conversation came from a store, I'd return it as damaged.
