Where did you come from? What is the nuance of this emphasis? I could understand it if the emphasis were on where.

Here are two instances in a formal paper I submitted where my professor told me my semicolon usage is incorrect. (For the record, he told me this as he was reading it for the first time. He said most students use semicolons incorrectly and to avoid them altogether. I'm not .)

Perhaps the term "brown" refers to the tendency of people to do their thinking in the can? (just joking)
