Lunar Cycles: A Conversation with Luke

In the car on the way home.

• Me: What did you learn about in school today?
• Luke: We talked about the moon! It’s up in the sky at night.
• Me: It is. Did you learn anything else?
• Luke: The moon comes in different shapes, like circle moon and crust moon.

Obviously, he meant crescent, but crust (as in the pizza crust he doesn’t eat) is also applicable.
