Superhero: So that's what sushi is! It's raw fish!
Me: Not all sushi is raw, and not all of it is fish. Aunt Tabitha likes some sushi, and she's a vegetarian.
Superhero: Aunt Tabitha is a vegetarian?
Me: Yes, and so is Zara.
Superhero: Zara is a vegetarian? She is an animal doctor?
Me: That's a veterinarian. A Vegetarian doesn't eat meat.
Superhero: Oh, THAT kind of vegetarian! I wondered what an animal doctor had to do with sushi . . .
