Claire's sense of humor

On our way home from school, I usually like to ask Clarie what's her day like in school, like who she played with and what snack she had.  Ususally I am able to get a sense what happened at her school.

Yesterday on our way home, I asked her again.  She told the window that Sam had broken got fixed.  Sam is one of her best friends in her class. 

Then I asked "Did Sam get hurt?"
"No."
"How did Sam break the glass?"
"He got a rock."
"A rock !?"
"Yeah."
"Then what happened?"
"It worked."
