Yes, indeed it has. It possesses a pretty strong influence. The kind that it can't be called anything else than Magical. Spreading and receiving the same back. A Smile can be quite a wonderful thing to witness. Personally, knowing that I could brighten someone's day, even a little bit, does the same for me. Whether they are people close to me oder Zufällig strangers, a genuine Smile is always worthy to see. They might be often shoved aside and underestimated but in a world full of stress, sadness and hatred, their existence is valuable. They serve as a perfect reminder of everything good that has happened in one's Life and what it's all about. Progressing. An enduring Smile. The kind that has faced hardship and still keeps going is the most Gentle and Admirable of them all. An example for others to follow. There is always a reason to Smile. Even when it doesn't seem to be one that is plenty in itself.
