Mentors and apprentices are partners in an ancient human dance, and one of teaching's great rewards is the daily chance it gives us to get back on the dance floor. It is the dance of the spiraling generations, in which the old empower the young with their experience and the young empower the old with new life, reweaving the fabric of the human community as they touch and turn.
