At the airport for his 9-year-old son's first big trip by himself, after checking in on the phone with Grandma and Grandpa.
Dad - "So what did Grandma say on the phone?"
Son - "She said I love you, can't wait to see you, we're going to have so much fun...and...uh...something about 'We will rot you?'"
Dad - "Do you mean 'spoil you?'"
Son - "Yes! That's the word. I couldn't find it in my brain."
