The Castle?

Violet and I were having dinner, while Christie was at work.  In the middle of eating, Violet said, "Daddy, ask what I do."
It took me a minute to realize that she wanted me what she did that day, as I normally ask her at dinner.
"OK, Violet, I haven't asked you yet, have I?  What did you do today?"
Violet put on her sly smile and said, "I do knocking down the castle."
No idea what she was talking about.  "The castle?  What is that?"
"It was a accident," she said.
A castle?  In Violet's imagination that could be anything.  I made a mental note to look around for new broken things and hoped that "the castle" was made of legos.
