Someone handed out a paper that looked excellent, I read it before he read it aloud, and I didn't believe he wrote it. It was too good and seemed above something a high schooler would write. I changed my mind and believe he wrote it when he read it aloud because the way he read it, he owned it. He read it just like it was something he wrote himself. After he was done the teacher said "that was good, but you didn't write this, you downloaded this from the Internet." She didn't ask him, she didn't check, she just publicly accused him. He looked shocked and said "No I didn't!" where she just kept insisting he did without any proof whatsoever except that the paper was just good. She may have just blindly failed him on the assignment.
Off topic but other student in this assignment handed out another paper which was full of misspellings and grammatical errors. Absolutely chock full of them, to the point you could hardly read it. After she read it, the teacher said "there's a lot of misspellings" to which she protested "my computer doesn't have spellcheck." She really thought this was a legitimate excuse, in English class. Like not having spellcheck excuses you from 1) proofreading and 2) picking up and old fashioned paper dictionary.
