I had a neighbor who when he didn’t like something would call the police (usually he just didn’t like cars parked on the street). He was cranky and never smiled. I started waving at him and my children did the same. Eventually, he started to wave back and we would talk. The neighbors looked confused when they saw me talking to him, since he was “mean” and “not a nice person” (sounds redundant, but I was quoting different people). His house is up for sale now. Last time I saw him he was very complimentary and hugged me goodbye. Maybe Elizabeth Edwards should learn sometimes being nice to someone can make them nice to you.
