What or who, makes a good friend? Is it someone who says nice things behind your back? What are the attributes of healthy and unhealthy friendships? Does your friend always need to tell you what you want to hear? What if their honest feedback is something you don't want to hear? Should they hold back or speak up? And what about those 'friends' who vanish when you're no longer valuable to them? When you've reached your use-by date? And when does a relationship progress from someone 'you know' (via circumstance, situation or proximity), to a friendship built on trust, respect and love?
