Today, walking to lunch, I found a note on my car excoriating me for not pulling up two feet closer to the crosswalk, making a bigger space for the sizable SUV that had wedged itself behind me. The second page of the double-layered chartreuse post-its offered up only the word Jerk! I felt guilty. Then resentful, and started generating comebacks. Several blocks later I realized I still might have moved my Subaru a little so the person behind me could leave more easily. But I hadn’t bothered, hadn’t even considered the possibility.
