As I tend to do from time to time, I said something vulgar, then realized that one of the girls was close enough to overhear me. I apologized to her dad, and he said, "That's okay. She knows all the swear words. But she also knows better than to fucking repeat any of them."
She enthusiastically added, "It's true. I know all the bad words."
I replied, "I'm willing to bet you don't know all of them. I guarantee I know some words that you don't know, because I know some words that not even your dad knows."
"No. I know them all."
"Really? What's snoodling then?"
"I rest my case."
