Question Mark

The detail that struck me the most about Cho Seung-Hui:

"...on the first day of a British literature class last year, the 30 or so students went around and introduced themselves. When it was Cho's turn, he didn't speak. On the sign-in sheet where everyone else had written their names, Cho had written a question mark.
"Is your name, `Question mark?'" classmate Julie Poole recalled the professor asking. The young man offered little response."
