Don't . . . or says mother porcupine to elder son, father (?) to younger, one brother to another, mother to both. . . whereupon they do jump on the wall, and fall off (""NO! NO!"") and mama kisses to make it better -- which might have been a conclusion of sorts; but this straggles out into another warning, another spill, another ""OH, NO!"" Compounding the confusion between badgering (""No, don't throw it. You'll lose it""), enjoining (""Don't hit him. He'll cry"") and danger-warning (before the fall) is the difficulty of knowing who's talking, sometimes of knowing who's who. No form, no function.
