The following is a not-atypical conversation I had with my 4-year-old son D- the other day on our way to the library:
D-: Why are we going to the liberry?
Me (brushing the turnip leaves off my sleeve): The lie-berry? What's that?? Is it like a blueberry or a strawberry?
Me: Should I go look for a lie-berry bush so I can pick me some lie-berries for a delicious lie-berry pie?
D- (scolding): You know what I mean! The LIE... b... (pause) ...erry.
Me: Mmmm, sounds yummy!
D- (giving me a well-practiced blank look as if I'm a hopeless idiot*): It's not.
