So, we're making selections from a list of "vital needs" - the things you need to have in your life in order to be happy, or at least satisfied. Firstborn has just finished looking them over.
Firstborn: "What is unstructured or structured time?"
Me: "Structured time is time with planned activities. Unstructured time is time when you get to do what you want."
Me: "Like, I have unstructured time. Maybe I'll play some video games. Maybe I'll take a bath. Or maybe I'll read a book. Or maybe I'll run down the street naked with a piece of fried chicken in each hand."
Beautiful Wife: "Don't run down the street naked with a piece of chicken in each hand. That's illegal."
Me: "There's a fine line between 'unstructured' and 'illegal'."
Firstborn: "...And running down the street in a bathrobe would be right on that line."
Me: "Exactly. Running down the street naked would be waaaay over it."
Firstborn: "An uneaten piece of fried chicken in each hand!? That's way over the line!"
