Last November, I gave some volunteer drawing classes at a school. Since I had limited space, I had to pick and choose a small number of 9-10yo kids, and asked the students interested to do a drawing and answer "Why would you like to participate in the drawing classes?"

One of the kids used chatgpt or some other AI. One of the parts that gave it away was that, while everyone else wrote something like "I want because", he went on with "By participating, you can learn new things and make friends". I called him out in private and he tried to bullshit me, but it wasn't hard to make him contradict himself or admit to "using help". I then told him that it was blatantly obvious that he used AI to answer for him and what really annoyed me wasn't so much the fact he used it, but that he managed to write all of that without reading, and thought that I would be too dumb or lazy to bother reading or to notice any problems.
