Did you ever notice that a smile isn't just the position of you mouth? When most of us smile, we use our whole face. We smile with our eyes, even if they aren't wide open. When I see someone smile, it makes me happy. How about you? Do smiles brighten your day?
When I see someone who isn't smiling, I try all the harder. I smile every single day. Why? Because it really is contagious. You'd be amazed at how many smiles will show up as a result of yours!
Now I am not saying to be cold and uncaring about someone's bad moments. People you encounter might be going through financial or health difficulties or may have just been touched by the death of a loved one. You can still smile a kind of loving and caring smile. Let the world you encompass shine!
