Student (a seventh-grader): I wouldn’t eat vegetarian pizza - all it has is crust, sauce, and vegetables.
Me: And cheese.
Student: No. A vegetarian pizza.
Me: Right. It’s not vegan, so it has cheese.
Student: No, it doesn’t.
Me: Why do you say that?
Student: [Looking at me incredulously] Hello! Cheese is a vegetable.
Me: [Laughing] What?
Student: It comes from the ground!
Me: No, it doesn’t. It comes from milk. It’s a dairy product.
The funny thing about that is that even if cheese was a vegetable it would still be on a vegetarian pizza.
