A smile is a form of body language — simple and uncomplicated, yet deeply meaningful and powerfully influential on those who receive it. When we are moved by something, we simply offer it a smile. When we are tired or disheartened, just a smile from family or those around us is enough to keep us moving forward with hope. No matter how poor or difficult life may be, it doesn’t mean we cannot smile, because the happiest smile doesn’t have to be bought with the most expensive things — it can come from the warmth and goodwill that one person offers another. The smile of a single person can bring happiness to many and inspire them to smile in return, and a smile is also the beginning of the beautiful friendships we share with one another.
