“Interaction may begin for quite different reasons. One or both persons may know something about the other and, on the basis of this information, may (anticipate that interaction would yield good outcomes. This would result in a deliberate decision to seek out the other person and interact with him. Under other circumstances the two persons may be thrown together by the operation of factors beyond their control. Their jobs may bring them together, common friends may introduce them, or residence in the same neighborhood may result in a chance meeting. In these instances interaction is begun in response to the immediate situation without any necessary anticipation of the possible consequences by either participant.”

Context: If it is empty to ask Negro or white for patience, it is not empty — it is merely honest — to ask perseverance. Men may build barricades — and others may hurl themselves against those barricades — but what would happen at the barricades would yield no answers. The answers will only be wrought by our perseverance together. It is deceit to promise more as it would be cowardice to demand less.
