There is nothing more important I can imagine doing that challenging the students I have to think more deeply about what they do and say, and what they do not do and say. Both our actions and our in-actions are important. I remember the words of Martin Luther King, Jr: "In the End, we will remember not the words of our enemies, but the silence of our friends."
I seek to challenge, but also to empower.
Then my students have choices.
If I have a legacy, it is that my students have the opportunity to be thoughtful citizens of the world we leave to their charge.
Peace.
