I don't even know where to begin. Last year, my first year of university, I was in a Literary Science 101 (I study Dutch literature) and I was to analyze a short part of a sentence as a literary analysis technique. Now, in the department, much emphasis lies on being able to 'dissect' sentences grammatically. There was one word left ('very') and the professor gave me two options (so, basically, it was an easy 50/50), AND one of them was a verb construct. And I replied: "Uhm, I don't know."
I got a 15-minute rant on how ridiculous that was, and I was too embarrassed to ever participate again.
A few months later, at the end of the year, I finished his class in the top 3 and I'm his personal student assistant now.
Anything can happen, don't worry about it.
