1) DD was reading a book and laughing her head off. It turns out she finds this book irresistibly hilarious:

2) DD has decided that it's about time I learned proper English:

Me: "Go wash your hands. Your hands are all sticky."
DD: "Do I need to use soap?"
Me: "No."
DD: "Then why didn't you tell me to RINSE my hands?"

Me: "Let's scrub these so they'll be shiny again."
DD: "You mean polish."

Me: "Look at those sparkly shoes!"
DD: "They are called light-up shoes."
