How many people push their chair in when leaving a table at a restaurant, even a fast food restaurant? Something learned in basic training, and it stayed with me 50 years later.
Do you know how many people walking on a sidewalk walk out of cadence? Pedestrians need someone to walk alongside saying, "Leyft, leyft, leyft, right, leyft." Just my obsessive nature. Don't mind the Southern pronounciation of "left." My attempt at authenticity.
