un effort

12a Des gamins pétrissaient une grosse boule de neige, la posaient délicatement sur une couche bien unie et la poussaient avec prudence.

12b Le gamin la poussait d’abord de la main droite, puis de la main gauche, puis avec ses deux mains, puis enfin avec ses pieds et ses mains.

12c Tu accourais. Vous unissiez vos efforts, et bientôt, l’énorme bloc creusé de deux yeux devenait un bonhomme imposant.
