Ethan: What time is it?
Me: Nine oh four
Ethan: Why do people say “oh” when it’s zero?
Me: I don’t know, I guess because a zero and an “o” look alike
Ethan: But a zero is round and an O is an oval, right?
Me (thinking): Ah son, if Grampa Luoma was here, he’d be calling you a “Literal Luoma” right now.
Me (saying): “Yup, you’re right.”
