Put a smile on many faces, every day you can.
At coffee shops and outdoor dining locations, I find a table with 4 to 8 people over thirty and place my hands gently on two of their shoulders:
"Keep it down here. We don't want any trouble." It has never failed.
A young man sitting with his wife and child or children: Hand on his shoulder: "You're a lucky man. Dr. James Dobson, founder of Focus on the Family, said, 'There is almost nothing a father can do wrong if he shows his children that he loves their mother'."
It has never failed. Big smiles, big joy. Wonderful lesson.
