Sometimes a stranger comes to the village and tells the village a story, and the village rediscovers something. Opportunities for rediscovery of ourselves may also be rare, but we should seek them out if we are to flourish and grow. It's not easy though, and safety and curiosity are not naturally comfortable together. But it can be refreshing to surprise yourself and others.
Metaphorically, you might say, some people will stop to look in a mirror to see what they could learn, while others will hurry past it, in case they learn something.
