The above is for my own guidance; what follows is for the children.
"Children, how comfortable we are here! Everything is clean; everything is in order; I am so fond of you; you are so fond of me. Isn't this true, children?
Children.—I am, I am. Me too (correct).
Tell me, Gino, are you cold? You said no at once. Well, no, you are right; we are really very cozy here. There, in that corner (I point) there is a thing which gives out much ...
Children.—Heat. It is the stove.
But outside, where there is no stove, over there, towards the horizon (the children are to a certain extent familiar with this word), there is no warmth.
Children.—It's cold there (an answer due to the clarity of the laws of contrast).
Last night ... while we were asleep, while your mother perhaps was mending your clothes ... dear mother, how kind she is!... well, last night, so many, many white flakes fell softly from the sky!...
Snow, snow! exclaim the children.
