People lose their minds during a snow storm. I have witnessed neighbors arguing about snow removal too. The end of my driveway is double apron that's shared with the next door neighbor. The one time I got home from work early and was out shoveling. I cleared the entire driveway and the neighbors wife was livid because I tossed some of the snow onto their front lawn area. I think I just went inside and told them they can shovel their own side next time.
