is how you slice watermelon on a school campus. It's plastic, and you would have to try very, very hard to injure a person with it. I didn't let anyone else even touch it and kept it in closely guarded custody.
I didn't know whether to be amused or exasperated by the 7th-grader who insisted that I could not slice watermelon with a plastic knife, notwithstanding that I had already sliced up four or five that day before having that conversation with her. A lot of junior high kids struggle with the intersection of reality and their concept of it.
