Two Nuns Discuss Teaching
An eager young nun and a wise old nun were discussing teaching over lunch. The young nun was waxing enthusiastic over the privilege, but also the responsibility, of forming young minds. The old nun took a glass of water, inserted her forefinger, and agitated the water. Suddenly she removed her finger and the water immediately returned to its quiescent state.
That, said the old nun, is what teaching is like.
