Your enemy keeps clear of you. He neither grants nor claims favors. He awards you your rights,--no more, no less,--and demands the same from you. Consequently there is no friction. Your friend, on the contrary, is continually getting himself tangled up with you "because he is your friend." I have heard that Shelley was never better pleased than when his associates made free with his coats, boots, and hats for their own use, and that he appropriated their property in the same way. Shelley was a poet, and perhaps idealized his friends. He saw them, probably, in a state of pure intellect. I am not a poet; I look at people in the concrete. The most obvious thing about my friends is their avoirdupois; and I prefer that they should wear their own cloaks and suffer me to wear mine. There is no neck in the world that I want my collar to span except my own. It is very exasperating to me to go to my bookcase and miss a book of which I am in immediate and pressing need, because an intimate friend has carried it off without asking leave, on the score of his intimacy. I have not, and do not wish to have, any alliance that shall abrogate the eighth commandment. A great mistake is lying round loose hereabouts,--a mistake fatal to many friendships that did run well. The common fallacy is that intimacy dispenses with the necessity of politeness. The truth is just the opposite of this. The more points of contact there are, the more danger of friction there is, and the more carefully should people guard against it. If you see a man only once a month, it is not of so vital importance that you do not trench on his rights, tastes, or whims. He can bear to be crossed or annoyed occasionally. If he does not have a very high regard for you, it is comparatively unimportant, because your paths are generally so diverse. But you and the man with whom you dine every day have it in your power to make each other exceedingly uncomfortable. A very little dropping will wear away rock, if it only keep at it. The thing that you would not think of, if it occurred only twice a year, becomes an intolerable burden when it happens twice a day. This is where husbands and wives run aground. They take too much for granted. If they would but see that they have something to gain, something to save, as well as something to enjoy, it would be better for them; but they proceed on the assumption that their love is an inexhaustible tank, and not a fountain depending for its supply on the stream that trickles into it. So, for every little annoying habit, or weakness, or fault, they draw on the tank, without being careful to keep the supply open, till they awake one morning to find the pump dry, and, instead of love, at best, nothing but a cold habit of complacence. On the contrary, the more intimate friends become, whether married or unmarried, the more scrupulously should they strive to repress in themselves everything annoying, and to cherish both in
