What sort of cognitive failure leads to someone copying and pasting a paragraph from a website into their paper, and then, when called on the plagiarism, claiming "I didn't do it intentionally."
What the tea party does that mean? You didn't cut and paste intentionally? You didn't get caught intentionally? You used someone else's words without giving them credit. You didn't think that was plagiarism? Goddamn it, you idiot, that is the very definition of the word plagiarism. It isn't any other thing than what you, exactly, here, and quite intentionally DID.
And you have to do it now, when I'm already overworked? Now's when you drop this load of shit on me, and then you look all upset when I tell you that you have an F and you cry at me and you say you really, honestly, didn't mean to, professor Chiltepin?
You know what? You know what the F you earned stands for? It stands for "fuck you."
