A long standing argument in philosophy purports that friendship plays a considerable role in our self-knowledge and perspectives on the world, much of which can be accredited to the enduring influence of the Aristotelian conceptualisation of friendship. More recent thinking on friendship terminations has given cause to rethink and clarify the basis of such suppositions. This has particular relevance within the realm of childhood where "friendship termination" is considered a common experience. This article seeks to remind us that friendship can also blind us to the faults of others. We may believe the friend to share the same set of values and commitments, but we can be wrong: we may see our friend through the proverbial rose-tinted glasses and fail to spot the ways in which the friend actively damages our well-being. I concentrate on four interlinked grounds for dissolving friendship (estrangement, change, mistaken friendship and false friendship) within the realm of childhood so that we can better examine the role of school policy in this area.
