Doing things merely because of their simpleness or ease never gained much traction with me as being a desired activity, so perhaps I can offer another reason to smile.
Let’s first consider what a smile can do for those to whom it is directed. Smiles can have a very positive impact on those who see them. From babies to adults, smiles breed smiles. Smiles can encourage those who are hesitant, comfort those who are worried, calm those who are afraid, and extend a hand of friendship to the friendless. A simple action like a smile can have a large effect on many people – except when it doesn’t.
I know it sounds like I’m arguing against myself here but hear me out. Sometimes, not often, smiles don’t have the desired effect. From babies to adults, not all smiles are returned or appreciated. My young daughter does not appreciate any attention from strangers, smile or not, and will usually set to crying if one tries to talk to her. Some of my other young children will get quite angry if you try to smile at them when they are already frustrated. They don’t want to be happy. They want to let you know how angry they are.
