Color Coded...

Here's the setting: At dinner, discussing best and worst parts (yes, Beaver Cleaverish, but still fun)

Youngest: The best and worst part of my day was having my friend over...
Me: Having your friend over was a worst part (because of how he had said it)
Youngest: No. The worst and best part of my day was having my friend over...
Me: You already said that
Youngest: Yes, but I wanted to make sure you'd understand so it's color coded...
