It is the middle of Michigan’s second polar vortex. My dog needs to go out so I am taking her for a walk in the subzero weather. I am coming into the end of my second year in medical school, feeling the grind, but aware that I have to keep my head up because the next three years are even harder. I see an envelop stuck deliberately in the snow beneath a bush. I pick it up. “Read me” it says. I look over my shoulder. Twice. Inside is a note of encouragement. It is helpful. Given the neighborhood and the density of med students here, I wonder if it was written by someone who understands the difficulty of the training. It sure seems like it. I share it with my class. They love it. That letter brightened many people’s Monday.
