Notice, for example, how people who have unusual hobbies, opinions, strong or unconventional behaviour, tend to congregate. They form clubs, hold meetings, and organise rallies where they can get together and discuss their enthusiasms common or problems. The important word is 'common'. They look for other people with whom they can share what in the normal run of events is regarded by relatives, friends and neighbours as an oddity. A crowd, even a small crowd, is reassuring. Probably all of us recognise a tension within ourselves between the two forces of individualism and conformity, for at the same time that most of us are going with the crowd, we tend to resent any suggestion that this is what we are doing. We feel a self-conscious need to assert our individuality as when the belligerent man at the bar informs his small audience, "Well, I say what I think." Or the wary stranger to whom we have just been introduced announces, "You must take me as you find me. I don't stand on ceremony."
