My 8-yr-old daughter was talking to my mom on the phone the other night, telling her about a wasp that landed on her, and didn't sting her. I overheard my mom say "You have a guardian angel...They're real." While they were talking, I said to my daughter "Guardian angels aren't real." She put her grandmother on hold, then said to me "You shouldn't say that. That's something that's important to Nana, and it's mean for you to say that." I told her she's right, and I apologized. I thought that was an amazingly enlightened thing for an 8-yr-old to be telling her father. It's a humbling thing when a second grader straightens you out.
