If you have lived on this planet long enough, it is likely you have days or moments that are as clear today as they were when they happened. One such memory for me was during my time at university in the 90s. I was in my second year, it was a spring morning and I was late for class. As I hurriedly wove my way around and through the other people walking to campus, I heard someone behind me shout out my name. I turned my head and found my friend Carolyn waving. In that moment I realized, in my rush, I had sped right past her on the sidewalk without even a glimmer of recognition. I gave her a big smile and a curt wave and turned around like a woman on a mission.

“Sorry, no time for a chat. I need to get to class,” I shouted into the air, “but let’s visit soon!”
