In the United States, we drive on the righthand side of the road, and we have many other standards of right of way. Yes, that’s obvious. We do this to keep traffic flowing with a minimum of crashes. The same rule applies to sidewalks and store aisles. Walk on the right side. Don’t pull out into the aisle until you’ve looked to see if someone is coming. Don’t park yourself in the middle of the path to answer the telephone or read your shopping list. Pay attention to the people around you.
Can’t we all just move along?
