If your temper is aroused and you tell them a thing or two, you will have a fine time unloading your feelings. But what about the other fellow? Will he share your pleasure? Will your belligerent tones, your hostile attitude, make it easy for him to agree with you? "If you come at me with your fists doubled," said Wood row Wilson, "I think I can promise you that mine will double as fast as yours; but if you come to me and say, "Let us sit down and take counsel together, and, if we differ from one another, understand why it is that we differ from one another, just what the points at issue are," we will presently find that we are not so far apart after all, that the points on which we differ are few and the points on which we agree are many, and that if we only have the patience and the candor and the desire to get together, we will get together.
