A sequel to an article posted five minutes ago.
I was thinking about that adieu again, "Don't let that smile get away from you", and I got another meaning from it.
Your smile is your own. It's unique. Sure, it can be similar to another's smile, but it's not a perfect copy of anyone's. And you have many different smiles, each with it's own qualities. So don't let it get away from you, and use it as often as you can.
Smiling is something that every single culture in the world has in commons. A smile is a universal code for letting people know you're happy. There are few other things in the world that are universal. Think about it. When you're happy, how hard is it to repress a smile? Extremely difficult, for me anyway. When I show people I understand something, I usually give them a "thumbs up" or a make the "ok" signal, index to thumb...but it's not an irresistable impulse. Even in monkeys, smiles are universal. It shows that you don't mean another animal harm...also that you're being submissive. Think of that what you will.
