Genealogies are admirable things, provided they do not encourage the curious delusion that some families are older than others. - W. H. Auden

Practical jokes are a demonstration that the distinction between seriousness and play is not a law of nature but a social convention which can be broken, and that a man does not always require a serious motive for deceiving another.

Two men, dressed as city employees, block off a busy street and start digging it up. The traffic cop, motorists and pedestrians assume that this familiar scene has a practical explanation – a water main or an electric cable is being repaired – and make no attempt to use the street. In fact, however, the two diggers are private citizens in disguise who have no business there.

All practical jokes are anti-social acts, but this does not necessarily mean that all practical jokes are immoral. A moral practical joke exposes some flaw of society which is hindrance to a real community or brotherhood. That it should be possible for two private individuals to dig up a street without being stopped is a just criticism of the impersonal life of a large city where most people are strangers to each other, not brothers; in a village where all inhabitants know each other personally, the deception would be impossible.

Almost all of our relationships begin and most of them continue as forms of mutual exploitation, a mental or physical barter, to be terminated when one or both partners run out of goods.

But if the seed of a genuine disinterested love, which is often present, is ever to develop, it is essential that we pretend to ourselves and to others that it is stronger and more developed than it is, that we are less selfish than we are. Hence the social havoc wrought by the paranoid to whom the thought of indifference is so intolerable that he divides others into two classes, those who love him for himself alone and those who hate him for the same reason.

Do a paranoid a favor, like paying his hotel bill in a foreign city when his monthly check has not yet arrived, and he will take this as an expression of personal affection – the thought that you might have done it from a general sense of duty towards a fellow countryman in distress will never occur to him. So back he comes for more until your patience is exhausted, there is a row, and he departs convinced that you are his personal enemy. In this he is right to the extent that it is difficult not to hate a person who reveals to you so clearly how little you love others.

About suffering they were never wrong, The Old Masters.
