Do you find yourself meeting someone on the road, and they wave. Now for some unknown reason you don't wave back, but instead nod your head. As if you're saying, "I gotcha." Now instead of noding, why don't we make ourselves wave. Those strangers might not see the nod, but they will see you smile while you wave. I always say to perk up someone's day, but think about all those people on the road who think they are at the end of theirs. You can make a differnece....one wave and smile at a time.
