"Suppose that two men are doing paperwork jobs in an office. According to the office rules, each should do his job by himself, or, if he needs help, he should consult the supervisor. One of the men, whom we shall call Person, is not skillful at the work and would get it done better and faster if he got help from time to time. In spite of the rules he is reluctant to go to the supervisor, for to confess his incompetence might hurt his chances for promotion. Instead he seeks out the other man, whom we shall call Other for short, and asks him for help. Other is more experienced at the work than is Person; he can do his work well and quickly and be left with time to spare, and he has reason to suppose that the supervisor will not go out of his way to look for a breach of rules. Other gives Person help and in return Person gives Other thanks and expressions of approval. The two men have exchanged help and approval." (Homans, 1961:31–32)
