Generally and in the normal situations, human beings feel the need to belong and to be accepted by others. This is not explicitly manifested in our interactions and awareness. In day-to-day interactions we often behave socially simply because we must, in order to achieve non-social goals: like being served at a restaurant, or asking directions to a party we are late to. These task-driven interactions are social because they comply with the rules of interaction of society. Robot companions on the other hand need not affiliate with others, nor fulfill any inner need to be accepted.
