This is a quick post written out of a sense of loss and regret. A high-school friend of mine just informed me that our Senior year English teacher passed away. Reflecting on her memory we both felt somewhat ashamed that we hadn't kept in touch, or at least made the attempt to let her know, as we went on in years, of the influence she had on our lives.
Everyone has people in their lives that have a direct and lasting impact on shaping who they are. Siblings, parents, teachers, mentors, authors, thinkers, whatever. Do right by them and yourself and take the time to say "thanks". Both of you and the world will be the better for it.
