I was out with my sister on Saturday, and she was backing into a parking spot and these two old dears stood waiting. I smiled and waved at them, and one of the ladies, her face lit up like a Christmas tree. She had a smile that from ear to ear and beyond. She kept waving and giving a thumbs up, then nudged her friend and waved again, pointing over. It was so nice being the reason that she smiled. I may have made her day, or week or month or even year. I hope she thinks of that happiness every time she feels upset. It makes me feel so good knowing the effect I had on her.
You can do that too. Give a smile, receive a smile.
