I was once in the company of a grave, decorous, and well-dressed person who fell helplessly into a stream off a stepping-stone. I had no wish that he should fall, and I was perfectly conscious of intense sympathy with his discomfort; but I found the scene quite inexpressibly diverting, and I still simmer with laughter at the recollection of the disappearance of the trim figure, and his furious emergence, like an oozy water-god, from the pool. It is not in the least an ill-natured laughter. I did not desire the catastrophe, and I would have prevented it if I could; but it was dreadfully funny for all that; and if a similar thing had happened to myself, I should not resent the enjoyment of the scene by a spectator, so long as I was helped and sympathised with, and the merriment decently repressed before me. I think that what is called practical joking, which aims at deliberately producing such situations, is a wholly detestable thing. But it is one thing to sacrifice another person's comfort to one's laughter, and quite another to be amused at what a fire-insurance policy calls the act of God. And I am very sure of this, that the sane, healthy, well-balanced nature must have a fund of wholesome laughter in him, and that so far from trying to repress a sense of humour, as an unkind, unworthy, inhuman thing, there is no capacity of human nature which makes life so frank and pleasant a business. There are no companions so delightful as the people for whom one treasures up jests and reminiscences, because one is sure that they will respond to them and enjoy them; and indeed I have found that the power of being irresponsibly amused has come to my aid in the middle of really tragic and awful circumstances, and has relieved the strain more than anything else could have done. I do not say that humour is a thing to be endlessly indulged and sought after; but to be genuinely amused is a sign of courage and amiability, and a sign too that a man is not self-conscious and self-absorbed. It ought not to be a settled pre-occupation. Nothing is more wearisome than the habitual jester, because that signifies that a man is careless and unobservant of the moods of others. But it is a thing which should be generously and freely mingled with life; and the more sides that a man can see to any situation, the more rich and full his nature is sure to be.
