Caitlyn: "There's mail that you get, like a letter in the mailbox. And there's male like a boy. Isn't that odd, that it's the same word?"
Me: "Yes, but the words are spelled differently. Mail, like letters, is m-a-i-l and the other one is male, m-a-l-e."
Caitlyn: "We are female, and Papa is male because he's a boy."
Me: "That's true. Female is spelled f-e-m-a-l-e."
Caitlyn: "And so there's fee-mail, mail that you have to pay for."
