Telling stories

Today I told dad a story:

"Once upon a time there were some cars and pickup trucks on the road.
And then there was a police car and a wolf. And the police car ran
over the wolf."

Dad: Is that the end?
Me: Yes.

[few moments later]
Me: Why is that the end?
Dad: You said it was the end. Is there more?

Me: Yes.

"... and then the police car tickled the wolf."

Dad: okay that's a better ending.
