I Don't Want to be Exturbed

My Schnicklefritz is known for many things but being quiet is not one of them--if he's not humming a composition of his own he's making explosion noises.  Today on the way to church the back seat was silent.  My husband assumed he was admiring the falling snow and asked him what he saw out the window.  The question had to be repeated.  Finally a little voice said "Daddy, I don't want to be exturbed right now."  We hoped the giggles from the front seat about this new vocabulary word weren't exturbing him.  Finally he announced "I just finished counting to 300 by threes."
