A good education isn't learning by rote, a good lesson isn't punishment for failing, a good outcome isn't in data and stats.
Healthy boundaries don't guard the gate, but can't be breached. Healthy relationships don't pledge allegiance, but can't be betrayed.
That's because a good influence is always willing to help someone so no one gets left behind, always happy to repeat something so nothing gets forgotten. They call it passing the torch.
So a good mentor is an expert at helping bad students, and bad students are the good person's responsibility. Not respecting the expert, not accepting the responsibility, might seem smart, but they're big mistakes. They call it making the grade.
