 Cocking &amp; Kennett (1998) argue against such a mirroring view in two ways. First, they claim that this view places too much emphasis on similarity as motivating and sustaining the friendship. Friends can be very different from each other, and although within a friendship there is a tendency for the friends to become more and more alike, this should be understood as an effect of friendship, not something constitutive of it. Second, they argue that the appeal to the friend’s role as a mirror to explain the increasing similarity involves assigning too much passivity to the friend. Our friends, they argue, play a more active role in shaping us, and the mirroring view fails to acknowledge this. (Cocking &amp; Kennett’s views will be discussed further below. Lynch (2005) provides further criticisms of the mirroring view, arguing that the differences between friends can be central and important to their friendship.)
