My house. Lunchtime. The kitchen table.
My sister has just fixed lunch for the girls and is telling them they need to eat their carrots before they can leave the table.
"Why?" asks my oldest.
"Because they are healthy for you," says Natalie, repeating my healthy food mantra.
"But how are they healthy for you?" my daughter persists.
"They're good for your eyes. They help you see better."
This explanation seems to placate her and so Natalie turns her attention to my other daughter who, after hearing this conversation, has taken one of her carrots and is holding it up to her eye like an astronomer with his telescope, searching diligently for a new star.
