You never know what kind of day someone is having. Giving them a little smile can make a huge difference. Sometimes all we need is to feel just a little kindness from somebody. So smile at someone; not just today, but at least once a day. Challenge yourself at least once a week to smile tenderly at someone who looks especially mean. Who knows what is going on in their life! Smiling makes you feel good and is such a gift for the person you are smiling at. The best gifts in life are free!
