Dad: Sam, what did you do today? How was school?
Sam: Good. Play friends.
Mom: What happened?
Sam: James throw dirt.
Mom: James threw dirt?
Sam: (serious) James throw dirt me. (pointing to his chest)
Mom: Then what happened after James threw dirt at you?
Sam: (big eyes). TROUBLE. James TROUBLE.
Mom: Uh-oh. Did Sam throw dirt?
Sam: No. Dirt bucket. Sam dirt bucket.
I'm not sure I believe that Sam didn't reciprocate...but at least he knows there'll be TROUBLE :) with dirt throwing.
