Sharing a smile is sharing a happiness. We know that feeling is very contagious. So instead of transmitting feelings of sadness, negative thoughts, we should transmit feelings of happiness.
Sometimes we are confused about what we want to share to make the atmosphere around us happy. But actually by sharing stories that are funny, fun, we also help build a happy atmosphere.
Sharing a smile sounds simple, but it has a big effect on someone who sees it.
With a smile, it also shows concern and respect for someone.
So don't keep our smile to ourselves. As much as possible smile with the people we meet. Maybe we can change someone's bad feelings to be more pleasant because they see our smile.
