I'm "that kid" in my physics class.
I don't really mean to be. Just nobody speaks up and I want to move on as quickly as possible so we can leave potentially early. So when the professor asks us a question, I wait to see if anyone will answer it and then I answer. It's kind of pathetic that nobody else will volunteer on fear of being incorrect, when there are probably 300 people in there. Not to mention what we're doing is painfully easy yet those sitting around me don't understand it. So I have to teach physics to my classmates after just learning it. Sounds like high school all over again.
