You had a writing assignment, and instead of writing it yourself, you used an AI chatbot to write most of it, then changed a few words. When you handed it in, your teacher was impressed and asked, "Did you write all of this yourself?" You said, "Yeah." Now it's sitting there as your best work ever, praised in front of the class, and your teacher is talking about reading it out. You didn't write it. A computer did, and you said you did. The words are good — better than yours — which is exactly the problem, because they're not yours, and you've now said out loud that they are. The lie isn't just the AI now. It's the "yeah."
