Mabel showed me an organic snack made from two round crackers stuck together with cheese, the same shape as tiny hamburgers. Mabel liked using her teeth to pry one round cracker carefully away from the cheese, separating the hamburger-shaped snack into two flat halves. These halves she then ate one at a time. Alternating with tangerine segments.
While eating we were discussing fire hats and hard hats some more. This caused Mabel to reach around to her bookshelf and (without hesitation or searching) she pulled out a thin paperback that had good illustrations of construction workers wearing hard hats in it.
