This jealous regard for ceremony and the proprieties of behaviour is seen in the enforcement of rules of politeness by children who will extend them far beyond the scope intended by the parent. A delightful instance of this fell under my own observation, as I was walking on Hampstead Heath. It was a spring day, and the fat buds of the chestnuts were bursting into magnificent green plumes. Two well-dressed "misses," aged, I should say, about nine and eleven, were taking their correct morning walk. The elder called the attention of the younger to one of the trees, pointing to it. The younger exclaimed in a highly shocked tone: "Oh, Maud (or was it 'Mabel'?), you know you _shouldn't_ point!" The domain of prayer well illustrates the same tendency. The child is wont, as we have seen, to think of God as a very, very grand person, and naturally, therefore, extends to him all the courtesies he knows of. Thus he must be addressed politely with the due forms, "Please," "If you please," and the like. The German child shrinks from using the familiar form "Du" in his prayers. As one maiden of seven well put it in reply to a question why she used "Sie" (the polite form of "you") in her prayers: "Ich werde doch den lieben Gott nicht Du nennen: ich kenne ihn ja gar nicht" (But I mustn't call God "thou": I don't know him, you see). On the other hand, God must not be kept waiting. "Oh, mamma," said a little boy of three years and eight months (the same that was so insistent about the kissing and hand-shaking), "how long you have kept me awake for you; God has been wondering so whenever I was going to say my prayers." All the words must be nicely said to him. A little boy, aged four and three-quarter years, once stopped in the middle of a prayer and asked his mother: "Oh! how do you spell that word?" The question is curious as suggesting that the child may have regarded his silent communication to the far-off King as a kind of letter. _The Enforcer of Rules._ Not only do children thus of themselves extend the scope of our commands, they show a disposition to make rules for themselves. If, after being told to do a thing on a single occasion only, a child is found repeating the action on other occasions, this seems to show the germ of a law-making impulse. A little boy of two years and one month was once asked to give a lot of old toys to the children of the gardener. Some time after, on receiving some new toys, he put away, of his own accord, his old ones as before for the less fortunate children. That the instinct for order assists moral discipline may be seen in the fact that children are apt to pay enormous deference to our rules. Nothing is more suggestive here than their talk among themselves, the emphasis they are wont to lay on the "must" and "must not". The truth is that children have a tremendous belief in the sacredness of rules.
