Small talk is far from "small" or trivial, says one expert. It is the "cornerstone of civility." "Small talk is really, really important. It helps us connect with people, and not just at holiday gatherings. If you make connections with people, it makes it much more difficult for you to treat them in an uncivil way. If you think about being kind to and connecting with people, people you engage in conversation, you're going to open a door for them, you'll let them step in front of you in line. You'll engage in more acts of kindness and fewer acts of rudeness."
