When smiles are still genuine

Ever wondered at times, you suddenly realise that a smile seem to be one of the most difficult task in the world....although its the easiest....:-)
There are those almost instantly could shine a smile at anyone,at any given time, and there are some could simply "put on" a fake one at a drop of a hat to get things done...others simply forget there's something called a smile...
I've guess the most beautiful, freshest , genuine smiles are from young ones...especially when the smile comes straight without being filtered by the white guards of thier mouths.
Reminds me of a jingle like song which I used to hear over the airwaves long time ago....a portion of it goes "Smile from your heart and let one smile make two"

Hope that put a smiley face on you:-)
