Concerning functions of friendship,which does not belong?

Question

Quizplus · Accepted Answer

The three other options (stimulation, affection, and ego support) all refer to specific functions of friendship that relate to emotional and social support, whereas symbolic interaction does not necessarily relate to this aspect of friendship. Symbolic interaction refers to the ways in which people use language and symbols to create shared meanings in social interactions. While this can certainly be a part of friendships, it is not a defining feature of what makes a friendship functional or supportive.
