Hi, @sycamore1209, I agree. Smiles and simple courtesy are free and easy to share. We never know the impact they may have on a stranger having a particularly hard day. Reminds me of what our ele. schl prin. said a lfetime ago to our faculty just before the first day of the school year: "Always be kind. You never know what troubles another may have just experienced before meeting him or her" I have never forgotten him nor those words. Smiles are much like other forms of kindness. We never know what ripples of comfort they may unknowingly spread.
