William shed some light on a few things for me recently. The liquid inside a cherry cordial is called "cherry sap."
And, "I know how rainbows go up."
"How?"
"Magic potatoes!"
How could I make that up? He was serious about both those things.
Today, Zoe was doing knock knock jokes with him. This is what I heard Will say, "Knock, knock."
("Who's there?")
"Grape."
("Grape who?")
"What a beautiful day!!!" :D
