This is going to be short and sweet!
When we were at the park the other day there were two "big kids" (5 and 8) making a camp fire. Harrison wanted to play too, so the little girl was explaining the rules of how to make one with sticks and stuff.
When he asked a question, she didn't understand and said "What?"
"Don't say what, say pardon!"
I had to walk away I was laughing so much.
I wonder where he's heard that before :)
