"Because mother'll say No."

"Why?"

"Because she _always_ says No, stupid."

"Why?"

"Oh, Davie, you _are_ stupid! I don't know why; I only _know_. Don't
you remember that lady that used to talk to Miss Humf'ay and play with
us? Well, when we told mother, mother said No, didn't she? and the
lady played with those abom'able red-dress children that make faces
instead."

"Will he play with the abom'able red-dress children that make faces if
we tell mother?"

"Of _course_ he will."

"Why?"

"They always _do_, stupid."

"Why?"

Angela ran back. "Oh, Miss Humf'ay, Davie is so _irrating!_ He will
say _Why_ ...."

There is a lesson for parents in that conversation, I suspect.
