plagiarism

Alivia
I am so pissed! I take online classes (10th grade) and my English teacher sent me a message saying so, you totally plagiarized #8, from blah blah website. I will be in contact with your facilitator to see what further actions she will want to take. This teacher assignments are the most fucking stupid thing. Write a 8 paragraph essay on a 4 line poem for only 10 points!!! Hell no im skipping this. So I copied like one sentence for this assignment that I had to write an essay on. Ok fucking wake up. Every student on this planet has plagiarized at least one sentence. She gave me a zero and won't let me turn in any work for the rest of the unit. Am I wrong for thinking she is overreacting?
