Nine-year-old girl: "Oh no, I lost my nail clippers!"
Me: "Why did you bring nail clippers to Mad Scientists Club?"
Girl: "Because they have a tiny knife on them."
Me: "And you need this because...?"
Girl, giving me a look of ultimate scorn, "in case I get kidnapped and tied up and have to cut my way free."
Me: "ah. It's good to be prepared."
Girl: "Yep, that's what I think."
