My child asks me if lobster are fish. I say no, they are crustaceans.
He asks me then why they are called “shellfish,” and suggests they are fish just crammed inside of shells. I don’t have enough energy to engage on the topic, so I reply not with an answer, but with a question. “Why do you need to know?”
“Because we can’t eat meat for Lent, but we can eat fish and if lobster are fish, we are all set.”
