Sigma Social Game: "Lead With Your Feet..."

When getting ready to motion you are "about to leave" someone or a group of people "lead with your feet" expressively forcefully motioning you are in effect "walking away" from a transpiring conversation and not seeking to continue talking; as you politely say something as "Well, I gotta get going and it was good talking, (God-willing); talk to you later..." and walk off discreetly and politely as you can NOT because you are afraid but because you do NOT want to unnecessarily offend and/or hurt people's feelings. Amen.
