Margaret told me her troubles. Her sister had rented a farm near the city for the summer and had offered to let Walter spend his vacation with her in exchange for such bits of help as he was able to render. But Walter had made up his mind to go to work in an office that summer, and, although he loved the country and had always wanted to drive a horse and go fishing, his mother's attempts to convince him of the wisdom of her choice were without avail. He would not listen to her reasons. She pointed to the health argument, to the opportunities for play, the free time, the driving, the fishing, and the fruit without limit. Knowing Walter as I did, I could not understand why it was so hard to convince him. But every story has at least two sides to it, and of this story I had heard only one. The mother was so concerned with giving her son her good reasons for going to the country that she never even thought of finding out his equally good reasons for going to the office. Presently, however, Walter came in, and my first leading question brought out the true secret of the disagreement. "What is there about working in an office," I asked the boy, "that you care so much about?" "Oh, it isn't working in an office that I care about; I just want to earn some money. I never did make any money myself, and now I have a good chance and mother won't let me." This was really too simple; here two sane persons had spent several days on the problem without coming to any solution. By placing Walter's services on the farm on a financial basis and making him pay for his board he managed to spend his vacation, healthfully and happily and profitably in every sense; and everybody was satisfied. Over and over again we are impressed with the fact that most disagreements between people--whether between adults or between children, or between children and adults--are due to misunderstandings. As soon as parents resolve not to treat their children arbitrarily,-- that is, on the basis of their superior strength and authority,--they adopt a plan of "reasoning" with them. This plan might work very well, if the parents only understood the children's way of reasoning, if they but realized that the child does not reason as do adults, that he reasons differently in each stage of his development. Our manner of reasoning depends very closely upon our language. But every significant word that we use has a distinct meaning in the mind of the individual, depending altogether upon his experience. As the experience of the child is very meagre, compared to that of the grown-up person, it is no wonder that our everyday remarks are constant sources of misunderstanding to children.
